After a tear down of my 2.0l engine I started the build up to the 2056 big bore upgrade. Having a Bridgeport I started with the (5) 3/8 oil galley plug on the block halves
Drilling a hole in the plugs and a slide hammer to remove the old plugs then started the installation of the new pugs I was able to order from Type 4 store.

Not everyone has or wants dropbox, I didn't even bother looking.
You can post pics here directly, you don't need a hosting service.

The plug on the rear of 1/2 side is very close to the flywheel, you have to make sure you're tapped deep enough, but you also must make sure to trim the backside of the plug.

Great advise Mark Henry, I did trim a second pipe tap for "bottom tapping" and the single hole on the back near the flywheel does not have a cross feed passage so tapping deeper is not an issue

I did try to post my video here but were too big, so I m going to reduce the resolution on camera or video extension

Yeah, that is a pain trying to view on a device without an account...Ill fix that for sure

Will be taking on similar soon. I know it's recommended to upgrade the oil galley plugs, i'm wondering how much this is best practice vs required? If they the existing have stayed in place 45 years, what makes them more likely to be problem now?

Posted by: rfinegan Jan 19 2021, 10:31 AM

Required, I would have to say NO

Best Practice. I'm sure the oil pressure on the plug can get high when you are pumping 50 wt oil on a cold day with a 30mm t-1 pump..Loosing a galley plug or having one leak can be time consuming at least to fix the leak and cost you a rebuild if the plug comes out at worst. This is an EZ prevention and low cost, so I can not see why it would not be done while building

We had a plug come loose while switching in a used engine to replace a broken one. No reason for it to come loose but it did. It seems like the smart thing to do if you are rebuilding.

UPDATE: Just received the Engine yoke for the HF stand from [url=https://ljaircooledengines.com[/url]. for under 40.00 (less shipping) bolted right on and woks fine with cheep engine stand or option to mount Desk top.
ALSO. I purchased a set of used Early Weber 44 IDF carbs with the roller accelerator pumps ( Italian ) I think they will clean up nicely . I also have set of IDF 40 with 32 vents from previous build to choose for this build. The 44 IDF have 36 vents. The last set of 44 with big vents really made the top end on the 2L pull hard.

The camshaft for my 2056 is the VW Type 4 Porsche 914 912E Basic 9530 Cam Kit and leaning towards the IDF 44 carbs. But not sure what vents to start with? Should work well with the Kerry hunter heads and Evo 2 muffler (still working out the details for the heads)

Though I have built an engine on that type of yolk, its made for T1 engines and for a T4 engine it puts a LOT of stress on the engine case especially when the engine is more dressed.

The better kind had a ring to let the case bear against. There is a very expensive one ($300) and a cheaper on like I have that has three spokes and a 1/2 ring. And for the life of me I can't remember who made mine. :/

Either way, I would not use that yolk for your engine build. Its rolling dice. You may be fine, or you may have a broken case. At the very least, weld a 1/2 ring around it for the case to bear against.

The entire engine should be built on the engine stand. You don't want to build 1/2 an then un-bolt it. And you really don't want to build the engine on a bench top. Being able to rotate the engine is very important especially when you are doing valve train geometry.

Here is the GOOD 5 arm kind over on Ebay for under $100. You should buy this before you go much further and the engine gets heavy and awkward to mount.

https://www.ebay.com/itm/VW-ALLEY-PORSCHE-911-VW-5-ARM-ENGINE-STAND-YOKE-made-in-USA/184633997262?hash=item2afd0b37ce:g:fY4AAOxySE9Q8yfe

I can't find who made mine (EMPI maybe?) and I can't google it up so it may no longer be available. On mine you had to cut the head off the engine stand and weld on the head that came with the yolk. No big deal.

Just don't use the kind that you have.

You can bend up and weld in another arm and make a 1/3 ring out of some bar stock. If you do, weld the 3rd arm in off-center as it could interfere with installing the one piston pin. I built or modified 5 out of the 7 stands I now have, one is for 996/7 and I'll be building another MY96 shortly.
Note this interference issue might just be type one, or is it 911....I forget offhand.

Today I started the engine balancing of the pistons. These are Keith Black 96 mm Pistons and were pretty close.

1) Weigh the pistons and list lightest to heaviest
2) Weigh the piston pins and list lightest to heaviest
3) Match pins to rods for average weights

All in grams

Pins:
1)104.85
2)104.82
3)104.75
4)104.93

KB Pistons

1)397.63
2)399.16
3)398.30
4)397.90

Final Piston and pins (after a little work)

1) 502.46
2) 502.70
3) 502.70
4) 502.69

For those with time on their hands , Will get the last .2 grams on the next pass of balancing because I have Free Covid time at home

Tuning on the Piston pins is a great plan.. I decided to keep the pins neutral and easily swapped on replacement, tear down or inspection if needed.. Great tip for next time

I was watching this thread close, until my recent purchase of a nice new oil tank and engine tin combo from MB911 for a /6 conversion. Guess I just ratcheted things up a bit. I will still be watching though

Today started making a test fixture for Split weight connecting rod measurements .Big end , small end ,and gross weight. Big + small = Gross If we have no loss in the set up ( easy enough to check)
I purchased my Rods from http://www.europeanmotorworks.com/pvw/024-102/type-4-connecting-rods/2.0+Liter+H-Beam+Rods%2C+5.160%22+-+Set+of+4
after preliminary testing they seem good out of the box (only weighed the Big ends so far)
The gross weight on the rods seem to be within +- 1 Gram on a kitchen scale (mine scale goes t o. 500 grams with a resolution of 0.01 grams) so I had to borrow my "cheff" son's scale

Big ends weight :

1)251.62 g
2)251.56 g
3)251.30 g
4)251.40 g

Small ends weight:

1)177.87 g
2)177.65 g
3)177.41 g
4)177.44 g

The ARP bolts seem to be with .07 grams of each other

UPDATE:

I have the internals all sorted and balanced and turning to the Crankshaft , Flywheel and pressure plate, and fan. I decided I WILL have each Zero balanced dynamically and together. This needs special equipment typically found a good speed shop/ machine shop. I think I have a local source.

I decide on a new flywheel. I have 2 older ones that look pretty good , but finding the spec the minimum machine to thickness shows some ?? Is the minimum 9mm or 11 mm (0.354331 or 0.433071 )
The two I measure came in at about the same @ 0.355 ( this would be minimum ) and should not be cut again. With the new one on the way I will measure the same way and post back my findings. No sense balancing a flywheel that will need to replaced in the near future or next clutch service.

The crank is still standard on the journals. I will get a light polish on them to get them ready for the new bearings.

Posted by: rfinegan Feb 2 2021, 04:46 PM

FWIW:

While waiting on the next round of parts and machining....

This 1.7 to 2.0 to 2056 upgraded started with a little knock at idle. With some hard street use the noise/knock increased. In a time, over 2 years and 20 to 25 k miles later I found bearing babbitt in the oil strainer.
Thinking this was a rod knock that I was unable to isolate but pulling the spark on the rod with the noise. And the fact I now KNOW it was a bearing failure at this point the engine was pulled an retired and a stock 2.0l with Factory Djet was installed in its place

This replacement engine runs good and starts in all weather on first try but the fun spirited driving was missed, so the tear down started on this 2.0l weber carbed track engine and this turned out to be the only failure noted so far


Attached Image

The Cam thrust bearing shown above has no babbitt material on the timing gear side. The cam was walking back and forth with each change of engine load. Under power it seemed OK. So while in there the plan to swap cam and bearings, this now turn into new pistons and rods. Now a full 2056 with rods cylinders pistons, lifters and heads. fuel by Kerry Hunter headers and Evo ii muffler and webber 44 IDFs. And to help ensure this failure is not going to happen any time soon an double cam thrust bearing is already in the purchased parts box.

Posted by: rfinegan Feb 4 2021, 06:22 PM

Tonight I had some time to kill....


Matched balanced the flywheel bolts, pressure plate bolts and rod bolts( these were really close already). All to .5 gram or better. Now I do not have to number the bolts when I send the crank flywheel and pressure plate and fan for balance. The bolts can be installed in any of the holes and balance will be maintained.

Thanks my friend, It has been as much fun sharing the process with the "World" as leaning how to do it your self.
I am still on track for Spring start up, and still on track for my expected Hp of 130hp (+- )

Was the top ring gaped too tight? What did you gap your rings at to resolve your issues? KB pistons? and about 002 -003 piston to cylinder clearances?

My heads are on the way to Jorge at EMW and looking forward to getting them back soon..(lots of good stuff to share)

Decided to change things up a little today. I decided to modify my oil baffle/widage tray. A few guesses where to places oil returns to keep the push rod tubes and valve covers full of oil during sustained high revs and let the oil drain back a little more freely. Opened the center louvers for the same reasons. I guess there is not wrong way to do this. But some mods are better then others depending on what you are trying to improve.

Stock tray keeps the oil from sloshing pretty good , but drain back suffers with "Hi revs" . Early engine 1.7 did not have this?

Step bit
Cordless drill
Sceatch owl (to her find the locations )
Cut off wheel in die grinder
Debur tool
Polish /Buffer on angle die grinder


I may have done this different on my second Mod ..but learning here as I go...

Trimming the 1.7 rockers for 911 elephant feet swivel tips. THESE ROCKER ARE HARD.

I had a 5/8 carbide ends mill to take 0.060 off the bottom of the rocker tip. Then used a 90 degree carbide chamfer bit ( carbide too) to cut another 0.060 bevel to allow the tip to rock when close to the rocker tip.

Here is the final result:

Tonight i decided to pull down the Old Weber 44 IDFs and get them cleaned up (rebuilt) before they are needed. Pretty standard results and dried gas. I decided to pull the lead Gallery plugs, which are prone to leaking and drill tap and seal the plug holes with 8mmx1.0x5mm fine set screws. (smaller metric plugs require less material removal before tapping)

@http://www.914world.com/bbs2/index.php?showuser=1435 did a fine write up on this here: http://www.914world.com/bbs2/lofiversion/index.php?t133490.html

I am very happy I decided upon this course of action as I found all kinds of solids in one in the wells/galleys Here:

This week was fabrication work: 2 1/8 exhaust pipe
I recently picked up a Pete weber 4-2-1 quiet Horsepower Header( looks a lot like an early Tangerine super header). I had the Evo II muffler with the Kerry hunter header.

But the KH is 1.5 in primary and the 2056 needs to breathe deep. The 4-2-1 is 1 5/8 primary and has stub pipes! The Outlet is 2 1/8. So I had to make the transition pipe to the muffler and add an O2 bung after the last collector.

Its tack welded together and will get the TIG torch out over the week end

Thank you @http://www.914world.com/bbs2/index.php?showuser=9712 . I went back to make sure of the muffler location before the final tack weld of the transition pipe beerchug.gif I think the set up is quieter then the SS heat exchangers and the Bursche muffler I had previous. But now I can feel the power band of the (stock cam/engine) start to pull in the upper ranges

While waiting on my parts I started with the cam and gear and clearance for the 30mm Schadek oil pump (T1)

Shortened the cam bolts for extra clearance :
1) 0.020 off the face of the cam bolt heads
2) Trimmed the rear of the cam bolts about flush with back of cam
3) Opened the oil pump outlet to match pump outlet
4) Hone cam thrust bearing for 0.002 end play
5) Cam spins freely on distributor side case half

I used a 3 sided hand scraper to scrape/carve the aluminum in the hole to the line and blended the rest back down into the hole. EZ small bits removed and little chance of messing up the pump saddle with a power tool
Also keeps the aluminum dust down till the final hone with a pencil wrapped with 600

Tonight, I fitted the second thrust bearing in the other case half. ( thrust bearing with tang) along with the center and rear cam bearings.

1) Remember to stone the back sides of the bearings. The stamped part numbers and sizes will displace material from the stamps and the bearing will sit higher there, deform and run tight.
2) The second thrust was tight and did not fit in the cam. I had to hone the thrust with 600 grit and flat surface. My Kurt Vice is a flat as I can get, hard steel surface. Hone with light spray oil 4-6 stokes on each side and try to install again. I keep with this procedure until the cam turns with no tight spots. Then proceed till I get 0.002 end play. Clean each time and light oil
3) Return to the other case half on the engine stand and stone the backs of the bearings.( I forgot about this)
4) Also remember to Tap the cam lightly with a soft brass or aluminum punch and dead blow hammer. 5 taps on each end to seat the thrust bearings in the case. Cam spins better with this and less drag!
5) Assemble cam and both case half. Test cam for spinning free. Mine would turn with screw driver OK..but more then before
5) Hand tight bold for case halfs. Same spin test. Light drag with large screwdriver in pump slot. OK but not great.
6) Tighten case bolts to 14 lbs. Spin test again. Same as above a little tight by hand and OK with screwdriver
7) 5 taps on end of cam wit head blow and soft punch. Spin test again. EVERYTHING GREAT. Spins EZ by hand. Check end shake. Small play of .002 Perfect

Tomorrow: drooley.gif
Bolt stretch of the ARP bold and plsti-gage the rod bearings. Install gear, bearings and pins. IF all well install cam, crank and case halfs.

ARP bolt stretch:

Following the instructions for messing bolt stretch required a $60.00 to $200.00 bolt stretch dial indicator. I will do my best to user a micrometer for this. peeps just a little better them guessing and generic number. 0.0005 to 0.00055 torque 30 lbs. I also plastigaged the cleansed the rods too.

1) Clean rod ends and mating faceless
2) Remove grease from threaded rod ends
3) Apply arp molly lube rod threads faces, bolts
4) Assemble cap and rod
5) Torque bolts to 15 lbs
6) Losen first bolt and measure base rod boot length. Tighten to to rod stretch is achieved. repeat for other rod bolt

MY results were:
base bolt measure : 1.8640
bolt stretch : 1.8580
difference : 0.00060 @ 28lbs
very close
I used 27 for my final torque and bearing clearance of 0.0015

You torqued and used the stretch gauge?
I've tested VW and Porsche ARP rod fasteners between 25 to 40 lbs and have found that I get the same result with both methods.

996 bolts (Carrillo and stock rods with ARP bolts) are 40 lbs, good thing the torque is accurate as 3 of 6 rods you can't get the stretch gauge on the bolt.

Posted by: rfinegan Mar 28 2021, 02:27 PM

Mark Henry , I did both. The first rod i did the bolt stretch method on the 2 bolts as I outlined. I used a User recommended 28lbs and both were 0.0006. (5 tenths too much). Being new to bolt stretch and not having the proper tool for reproducible results. I decided to do one rod with new stretch methods and compare with the traditional torque method. In the end I ended in used a torque of 27 pound feet on all the bolts. and only experimented with the first 2 rod bolts. All the others were installed one time with the torque method and done. Even the plastigage was done on the first 2 bolts

Posted by: 930cabman Mar 28 2021, 02:50 PM

I know there are no dumb questions, but,

I also have used Plasticgage for checking bearing clearance's and feel this method is reasonably sound. Bolt stretch: once a bolt is stretched with X# ft/lbs. and released does it return to it's untorqued length? and can you repeat the process and obtain the same result with the same bolt? Does the stretch measurement include any stretching with the internal threads in the nut?

BTW: thanks for documenting and good luck with the build

Torque-to-yield fastener
From Wikipedia, the free encyclopedia

A torque to yield fastener (TTY) or stretch bolt is a fastener which is torqued beyond the state of elasticity and therefore undergoes plastic deformation, causing it to become permanently elongated.[1][2]

Fastener[edit]
Torquing a fastener to its yield point results in a high preloading of the fastener which, depending on the load frequency and amplitude, can significantly increase the fatigue life of the fastener. When the applied load doesn't surpass the clamping force of the fastener, the strain of the fastener will be lower than when the preloading is smaller than the applied load. It is therefore beneficial in high-frequency high-load situations with a higher risk of fatigue related failure, like a bolted down cylinder head, to use torque to yield bolts.[citation needed]

Advantage: Compared to normally tightened hardware, a smaller sized TTY bolt/screw may be used while still maintaining the same clamping force.
Disadvantage: A drawback with TTY hardware is that it normally has to be replaced when loosened, for example when the cylinder head is removed.[3]

SO...I may have not followed the process of torque stretch or TTY as I did a bench test on the stretch method with just the rod. And I believe the bolts are one time use but the advantages above may be with it.

Anyone feel I should replace the 2 ARP bolts I did the stretch test on prior to installing? This is the same rod as the one I Plasti-gaged too

As far as I know, ARP rod bolts are not torque to yield (only their head bolts). Per their website you can reuse rod bolts which have not been permanently yielded more than 0.001" or otherwised look damaged. I wouldn't worry about replacing them personally. smile.gif

Edit: Should add I've never used them on a TIV, only bike motors (GSX-R600 and CBR600RR) and have reused multiple times without issue.

So, the shaft of the bolt is reduced in diameter, if so, the stretch probably occurs in this area and not within the threaded portions.

Also, look very expensive $110./pair of bolts 3/8" x 1.6"

Main bearing time:

ALWAYS measure your crank journals, case and thrust

I reviewed my previous owners receipts and build list and found the crank was installed with standard/.025 rod bearings no cuts to the case. So this is what i ordered. WRONG

1) The bearings I ordered were correct for the rods. I looked a set of shells on the old rods and confirmed the stampings on them at .25 and the rods fit perfect as seen owt the .0015 plastigage.
2) The mains had 2 problems:
a) The Silverline bearings I order were for the mains were wrong. Std, Std, Std. I needed .25, std, std and it ends up the mains were also cut to .25 mm
b) The box appeared to be unopened with a small cellophane tap in place keeping the box closed. I had an oil spill on my bench and the box soaked it up very well. soggy
Opening the box revealed the center bearing with multiple deep scratches in the babbit. Easily felt with finger nail and seen (see Photo)

This is the 3rd issue I had with the parts supplier for my 2.0l 914 and will not return or order from them any more...

The SOLUTION I now purchase all my parts from EMW (which I should have done in the first place). THEY ARE AWESOME! I have a set on .25 mains on the way from Jorge at EMW and will be here in a few days

While these may be useable (if they fit) But so were my originals and getting the crank polished deserves some good NEW bearings

IF anyone needs a set or part set of Standard main 2.0l baering please reach out to me. I can hook you up.

I had several intakes to choose from, but decided I'm am running the short manifolds and the larger opening for the weber 44.

This thing is going to breath! 6k should be pulling good with the Raby web cam 9530.

Else, I can put the 40 IDFs and the longer intakes and try for some torque. I wish I had access to a dyno for tuning..guess it will be seat of the pants or how white my wife's knuckles turn?

Latest setbacks include:

Defective Main bearing set Silverline
Wrong size main bearing set Std ,.010 and my crank is .010/.010 (my bad I went by the build sheet and did not measure)
Wrong type of main bearing set (type 1)received
Cheep replacement crank shaft distributor gear, key cut too shallow (damaged installing)
Damaged Crank gear ( when removing)

The new bearings were measured and cleaned up. I indexed for installation, and crank gear and distributor gear installed. I placed in prepped case half and everything spins fine. I placed the camshaft in and aligned the timing marks. Looking good. Turn the crank shaft and the cam pops our of bearings. DOH! Seem the gear had a few teeth that were damaged on removal and would not mesh well with the new cam gear. SO...I found a used set of gears and took the old ones off the crank (AGAIN).
The replacements are here and installed on the crank.
Time to assemble the 2 case halves....with pics and video

Well...you could always glue some strain gauges onto the axles and use two of these wireless amps/transmitters...

Of course you'd need something to save the CAN bus data and some other engine parameters.

Hi World,


I added the shims to my 2056 I took out of the engine to get a base line. Same crank and shims but new bearings. So cleaned the shims and installed new Flywheel WO seal and clean shims.


tight or just right? Do I hose the lube out with brake clean( dry bearing)?

This does not look right...Thanks for the feed back Mark Henry, and Ian Karr. I now have the familiar clunk when moving the crank...see new video for details

Finished the last 2 Pushrod measurements last night. Good news is a few of them are the same across cylinders. ODD however one (first cylinder) #1 had no shim. All the others had .015" , but the lenses are close to the same
I will measure them again and see if the if it was performed correctly. Others would not adjust zero lash unless I was much under the stock Push rod length . shim put it right in there

Looks like you have gone to great pains to get your geometry as (nearly) perfect as you could. I am also in the ranks of those who believe this is a vital part of the engine build.
I do, however, wonder what happens to this "perfect" rocker geometry as future valve adjustments are made.

I was getting ready to do a quick video on cutting push rods and while pressing the tip on may last intake push rod, I noticed it was much too long. About 0.030 inches too long.
WHAT WENT WRONG? All the others were within 0.001 of my desired final length. NOT a big a deal I got another one on the way. $9.95 but shipping was more than the part. But I wanted to be sure they were the same brand and I want a complete the set.

Seems I had "30" on the brain...my target was 11.300..I cut to 11.330. Wound be fine but i did not notice till I had pressed on the tip (IT IS NOT COMING OFF) It was not till I was cutting another push rod that I found out what my hang up on the .030 mark on the dial caliper was not "0" or .300

Working on the spacers for the rocker shafts . Number all the parts for each location to ensure they go where they need to go and the .003-.005 spacing clearance is maintained. THIS INCLUDED THE END Clamps. As they wear on one side (spring side)

I will get a video on this too ounce I set up the final Push rod cut length and confirmed.

Rebuild the early weber 44 IDF

Initial tune to:
55 idles jets
200 air bleeds
F11 tubes
36 vents
150 main jets


Will add the return springs, arms and Tangerine racing cams and cables on the install day. Also some extended Jet holders (just stacks). Maybe when I order the new jets on tune day

Need some cast 2 bolt air cleaner bases to match the top

Is the ID of those velocity stacks the same as the carb barrel ID's right at the top ?
Don't know what throttle linkage design you're using, but look closely.

My Dell 40's using the cross bar top plates resulted in the ID of the top plates being larger than the carb barrel bores. That resulted in a zero radius for air entering the carb itself. I made my own 2 piece velocity stacks. Had to be 2 piece as the lower part fit UNDER the cross bar top plate. This would not permit a well radiused inlet for the top part as not enough OD .

Yes my stacks (I have 2 sets) are larger then the OD of the top plate of the carbs . Will have todo some thing to make the transition better. Perhaps and insert like the ventures

I user a top air cleaner plate from a 40 pdf/ 1/2 stacks built in and matched it to the cast base for the air cleaners to help smooth the transition of the air cleaners and Velocity stacks to the webber 44 bores.

I think this will due till I get to a Dyno one day

Maybe just a little more chamfer on the top before the Chrome stacks? I can do that....

Did you buy the header from me? is it a 4-2-1?
I sold a Pete Weber header, that was missing the stubs, to a chap in the USA 10-15 years ago. It should make good power.
Did you get it ceramic coated? Totally worth doing on that header.

Posted by: rfinegan Jul 29 2021, 06:42 AM

I purchased the Pete Weber 4-2-1 Quite horsepower header with no muffler from a guy in OH that was included with a pack deal he got with a race car(you never know )

I have a set a of stubs but they are small and cheep but are working well on the 2.0 Djet right now. I have a set of Tangerine Stubs to match the 1 5/8 Primaries in the works but will not be ready for initial start up
These came wrapped, So I am going to run them as is.

Ceramic may be in the future...we will see how she runs
I talked to Chris at CFR (tangerine racing)a few times about this set up and he says the primaries are a shorter then his street header. I am hoping to make some good mid range and Top HP ( I see a Dyno pulling my future)

Best Regards

-Robert

The transmission is back together and feels good to get it back on the engine. Add starter and filled with oil. Pulled plug to crank engine over to build oil pressure. Even with the plugs out, I am still cranking slow. Jumper cables only. I installed the positive cable on the starter and things are better but still too slow. Looking at a Hi Toque starter next.
Its as slow as the the stock engine. So no surprises here. So I did a quick compression test (COLD)NEW) and 125psi across the board and 40 PSI oil pressure.

Exhaust was swapped over from the 2.0 and installed.

NEXT: FUEL pump and Ignition system for initial start up

Crank and prime again to get the oil flowing with out plugs .ITs craning better with the ground cable to the block/battery. Put the pugs in and can count the compression strokes wheel cranking..but pretty good (Better with ground cable)
HOWEVER...
The mail delivered the HITORQUE IMI starter today...so 15 min swap and crank with pugs in good and small gell battery put in last year!

Missed the timing by one plug wire...or it was it this way last time it ran?

Initial start did not fire but was popping and trying ...loosened the distributer and turned it and VROOM..Its alive...Continued with break in of cam. rings, etc @ 2500 to 3500 rpm
Synced carbs at 3k..and timing was @ 18 degrees and can not turn distributor any further. Will fix this on shut down.. Reclock the plug wires took care of this and now at 28 @ 3000
Smooth idea at 1k and good throttle response .

Next will be AFR with wide band O2 and idea mixtures.. So far the base setting look pretty good

On track for a FIRST drive this holiday week end! Good idle and seem to be responsive to throttle during break in. Smoooth running even before the tuning

I got a set of motor mounts off an another engine bar and EZ enough to get them swapped before the install

Have to wrap a header tube by the speedo and clutch cable

Have to replace the clutch cable( has a fray starting )

Oil change before road test ....Waiting on Filters

Swap Fuel pump for carbs

Did I miss anything?

Tonight did the final zero valve lash. and was balancing the Webers 44 at higher RPM.
To my surprise the engine was breaking up and not making any power.

Was my Main Jets too small?

I am a little embarrassed to say, the engine spins up very quickly and was bouncing off the rev limiter in the Hyfire VI AL

Good to know it was set much lower for the stock 2.0 engine and working as it should

Now its set from my new higher redline and well below valve float

OOOPS, been some time since I played with the settings.. EZ rotary dip switches in a side access panel

NOT too friendly of a place to get to when mounted in the STOCK ECU position by the battery

Glad I have it set and ready to go...for this week ends drive

Its the support that we get here from the 'World" that helps keep us going when things do not go as we expect. Like plug idle jets, just after setting the valve lash. WTF, it was just running fine and now 2 dead cylinders.

As ya'll noticed, I post my failures here too. I learn from them more that some of the successes.

The Wide band O2 tuning will be all new for me on the Weber 44 IDF, but not too far off from from of late model Tune port and feed back carbs/ ECUs of the 80-90 cars
Keep tuned if you like this kind of stuff

I did find a Dyno tune shop only 30 mins from my house. $100.00 and hour or $400.00 an 8 hour day
I bet I can gets some base line pulls and set the best timing in an hour time

I hear its all about tuning out the flat spot on transition from idle circuit > to mains

My 2.0 L had 44 IDF when I got it and the top pull was amazing but the transition was not so much. So, I traded out the 44 for 40 idfs with 32 vents that everyone recommends. The drivability was better but I always missed the strong pull and push into the seat that I had from the 44.

Im better at tuning now so here we go again...

Here is a video of the test drive

https://www.youtube.com/watch?v=zUeKvJrBFgo


More tuning and clean up coming soon. As you know these things NEVER END

I must say this combo seem to perform very well and not too much for the street driven driven car

Posted by: rfinegan Sep 24 2021, 06:17 PM

What happened? I had Ben here on Tuesday and he too drove the car for a short spin and it was driving out fine...Like the video. I put about 20 mile on her and is now about 100 miles total and did a fresh oil change just before.

2 problems under investigation

1) Heavy spark knock from time to time after spirited driving. Happens on over geared low RPM on tip in of throttle . not so much on down shift. Maybe lean carb or sticking weights in Malory ?

2) Heard what sounded like a dry bearing howl on idle that started to pull the engine down to a stall. put a few revs to here and noise went away This happened 2 times


...but every things seems to be pretty good till THIS:

Pulled the distributor on Thursday night to see it its sticking.. Pulled it apart and weights was just a little sticky but springs back k OK.. cleaned and lubed and reduced the mechanical advance to about 18*... SO 10 initial + 18 mechanical =28.. I was about 30 before. Maybe this will help. Installed and set up...but will not start. I tried lots of things but only popping.. IT tuns out I must have clock the advance plate 180* off?

YEP went out today at lunch and flipped the plate and installed. Started right up
set initial timing to 10* seem to be running OK...Went to check the timing at 3k

I increased the engine speed to 3k and started to set timing light to 28. Before I could find the mark, the engines startle clanging and clacking like somethings was loose in the valve train. Then that howl can back and pulled the engine to a stall .Restarted and engine had a miss fire turned out to be #3 and oil leak under car.. been dry to this point and now puddles

I pulled the valve cover and confirmed that the #3 intake valve was not moving and was stuck open. and pushrod was bent

Pulled Engine
Pulled head
Valve smacked the piston and bent intake valve. WTF! 3k is not floating the valves with double springs and rev limiter @ 6500. Never hit rev limiter at 6500

WELL in in this far, its getting bulled down to see if a spun bearing or something is causing the Howl.
I pulled the other head and Guess WHAt? Same thing. #1 intake kissed the head, looks like one time and bent the push rod and broke a pieces of the head by the push rod tube(it was bent)off the rocker

I noticed oil in the cylinder 1 with brass of bronze flakes and in the combustion chamber. This is odd as I just changed the oil and no metallic seen only the moly beack in lube( pretty good investigation for 4 hrs)

I will know more as I inspect the lower end in the AM

IS it possible the Howling dry bearing noise is the valve guide? possible too tight? Causing a tight valve not to close and hitting the piston as it comes up and is hanging open OR bending the the push rod as it tries to open the valve ? It did stall the engine


Lower end spins freely with the heads remove. One hand on the Fly wheel. IT will almost free wheels but it does have ring drag


What Do YA'll think is going on here? All theories welcome .o38 deck and 465 lift. I did check Piston to valve clearance and multiple valve lifts and recall it being good


IT will get fixed, but do not want a repeat performance


Posted by: barefoot Sep 25 2021, 06:52 AM

I'm using WEB 494 cam with 0.465 valve lift. no problem


How deep of a fly cut did you have put in? I have it apart and would be a EZ fix to ensure it does not happen again. OR CC volume would be helpful

thanks

Robert

Also IF fly cut I can swap the cam to larger if needed later....

Robert, this sucks sad.gif Sorry to see you having to tear down the engine after all the work, but you're attacking the problem with determination.

It looks like a valve interfered on the surface of the piston. In reference to barefoot's question, one technique used to verify clearance is to put some substance like playdo on the piston surface, install the heads, and then rotate the engine through a cycle. Inspecting the playdo afterwards can help confirm that you have sufficient clearance between valve face and piston surface. I can't recall if you did something like that before final assembly. If you don't have sufficient clearance you'd need cylinder shims.

I hope that makes sense.

Any one have an opinion of the condition of the lower end after break in and less that 100 miles?

I have never been in a fresh rebuild after only a few runs

Posted by: 930cabman Sep 25 2021, 04:41 PM

Never good news, but keep your head down and do the detective work as necessary. It looks as though the valves/pistons had contact, hence the bent push rods. Also, oil pump appears not correct. Best of luck with the repairs.

Posted by: rfinegan Sep 26 2021, 02:59 PM

Thank you every one who commented on the 2056 FAIL

Bottom end looks like everything is in good shape. Unless some on chimes in with comments on a failure i did not see I am going to reassemble the bottom end

The plan for the heads is to send them out to Gorge at EMW to get them ready to put back on. While I'm at it, I will send theKB pistons out with the heads and have them cut for valve reliefs . This is cheep insurance to keep this form happening again. and adult the rev limiter to about 6k...IM not making any power up above that. Double springs are good for way above that...so, Sounds like a good plan?

COST

2 push rods
2 Intake valves 44
Oil
Filter
assemble lube
Curl sealer
Piston Fly cuts
Weld 2 cracks in head by push rods. Bent pushups cam off rocker and punched through head


All in all, cheaper than the fix to my neighbors new F450 after hitting a deer at 70 mph
bumper 650
brackets 100
DYI

I guest Stuff happens, you just have to roll with it, fix it, and move on.. Things can always be a lot worse. beerchug.gif

I went back and looked at your thread and it looks like you had a deck height of .037. That should be sufficient (although most 1st timers shoot for an even .040 minimum). How did you measure that? You shouldn't have to have a relief cut in the pistons if you have a good, confirmed deck height measurement. Just keep in mind that relief will increase your combustion chamber and lower your overall CR.

I would also believe that the lower end is probably ok.

Whatever you end up doing, good luck!

Posted by: rfinegan Sep 27 2021, 06:21 AM

@http://www.914world.com/bbs2/index.php?showuser=17042

I think I have a video of the Deck height...

I used a dial indicator on a magnetic base to measure. Used a .100 parallel to find the zero on the indicator and then run the piston up to TDC or the smallest reading.
Smallest reading - .100= Deck height

Also reality check of a straight edge and feeler gage, gave the same value.

What happened? I had Ben here on Tuesday and he too drove the car for a short spin and it was driving out fine...Like the video. I put about 20 mile on her and is now about 100 miles total and did a fresh oil change just before.

2 problems under investigation

1) Heavy spark knock from time to time after spirited driving. Happens on over geared low RPM on tip in of throttle . not so much on down shift. Maybe lean carb or sticking weights in Malory ?

2) Heard what sounded like a dry bearing howl on idle that started to pull the engine down to a stall. put a few revs to here and noise went away This happened 2 times


...but every things seems to be pretty good till THIS:

Pulled the distributor on Thursday night to see it its sticking.. Pulled it apart and weights was just a little sticky but springs back k OK.. cleaned and lubed and reduced the mechanical advance to about 18*... SO 10 initial + 18 mechanical =28.. I was about 30 before. Maybe this will help. Installed and set up...but will not start. I tried lots of things but only popping.. IT tuns out I must have clock the advance plate 180* off?

YEP went out today at lunch and flipped the plate and installed. Started right up
set initial timing to 10* seem to be running OK...Went to check the timing at 3k

I increased the engine speed to 3k and started to set timing light to 28. Before I could find the mark, the engines startle clanging and clacking like somethings was loose in the valve train. Then that howl can back and pulled the engine to a stall .Restarted and engine had a miss fire turned out to be #3 and oil leak under car.. been dry to this point and now puddles

I pulled the valve cover and confirmed that the #3 intake valve was not moving and was stuck open. and pushrod was bent

Pulled Engine
Pulled head
Valve smacked the piston and bent intake valve. WTF! 3k is not floating the valves with double springs and rev limiter @ 6500. Never hit rev limiter at 6500

WELL in in this far, its getting bulled down to see if a spun bearing or something is causing the Howl.
I pulled the other head and Guess WHAt? Same thing. #1 intake kissed the head, looks like one time and bent the push rod and broke a pieces of the head by the push rod tube(it was bent)off the rocker

I noticed oil in the cylinder 1 with brass of bronze flakes and in the combustion chamber. This is odd as I just changed the oil and no metallic seen only the moly beack in lube( pretty good investigation for 4 hrs)



Something really strange here, can't imagine vale float at 3K rpm & valves should be almost closed anytime the piston is anywhere near TDC. Only thing I can think of is If somehow the dual springs weren't seated properly and coil jammed and pushrod got bent then causing valves to hang open.
Really far out situations, only badly mis-indexed cam, or way off lash adjustment otherwise in play, but the engine certainly would not run under either of these conditions. Can't imagine that the camshaft is mis-ground as both collisions occurred off same lobe ????
Any other thoughts here ???

Posted by: ChrisFoley Sep 27 2021, 11:25 AM


Those valve marks look like repeated hard contact.
If all the other setup dimensions were correct, you just didn't provide adequate valve/piston clearance.
When I set up an engine for a new cam, I replace my valve springs with rocker spacer springs and rock the engine near top dead center while repeatedly poking the valve against the piston. At some position before or after TDC, depending on which valve, it will reach the closest approach point. It's easy to measure piston/valve clearance from the outside that way.
I wouldn't go less than .080" and probably not less than .120" on intakes in most applications.
BTW, you can create the pockets you need with a hand held cutoff wheel worn down to valve head diameter. The location is well laid out already. wink.gif

Posted by: rfinegan Sep 27 2021, 12:28 PM

@http://www.914world.com/bbs2/index.php?showuser=209

Thanks for the feed back.. I will to check again once I get the heads fixed for sure.
I did do the light spring trick and remember reading to check at various rotation of the crank. Not set full lift. But I do not recall the distance. I think it was close to the minimum of .080 or just under you mentioned. Thinking the doubles springs should control my rpm range, I moved forward.

Will do the PlayDo trick to as a reality check.

It's odd the fails we're 1 and 3 intakes on the same lobe. And rear cylinders. IM thinking they kissed the pistons at some time on a high Rev and ran ok. Resulting in a sticking/ tight valve, when they got hot they stuck and failed? Else why did the front two intake valves on 2 and 4 touch too and bend pushrods?

Either way I think valve pockets is a good thing here. I know they touched at least once and EZ to do now that its apart.. I also have a Bridge port and some fly cutters. 20-40% bigger then valve sound about right to me. (44/38)

How deep can you safely pocket the top of a KB 96 piston? Enough to get the .120 or a set max amount.
This is better they playing with the DeckHeight as pushrods and geometry have been set

Best Regards
-Robert

PS. No hurry on the stub pipes, when ever they are ready is OK now...

Posted by: rfinegan Sep 27 2021, 02:31 PM

Here is a thought I seem to have been over looking....

The Piston to Valve clearance is not only to control clearance at high revs but for Thermal Expansion too. This seems to fit that the rear cylinders are the ones that failed. If I did not have enough clearance? I will increase the clearance to .120 + on both intake and exhaust with the valve notches in the pistons. Im pretty sure I used the minimum size here when I tested that . I will report what that was when I get it back together.

I am thinking the intake valve was .060 to .080 ish? I have no notes, but remember doing the press on the rocker to get the valve to touch the pistons at various locations.

I am thinking I was on the lean side of things too or high head/ combustion temps..I had spark knock only after spirited driving ,so timing and AFR testing was on the TODO but this failure peaked its ugly head happy11.gif

Posted by: rfinegan Jan 10 2022, 06:20 AM

Tips of the Day:

When installing the last lock ring for the pistons pins, place a rag under the piston before installing/ trying to install the lock ring.

* Best case, the rag will catch the pin when you drop it or it flys off.
* Worst Case, you forgot about the rag and the lock ring falls inside the engine case

Good news is it only took 30 mins to pull the piston /cylinder and go fishing with a magnet to get the lock ring out of the case

What is your piston to valve clearance?

Posted by: rfinegan Feb 2 2022, 10:55 AM

With the new 0.050" valve notches in the pistons I think it end up being :
Intake @ 10 degree first opening. 0.150 in min piston to valve clearance
Exhaust 10 degree before closing. 0.118 in min piston to valve clearance

How long did you crank the engine before the oil pressure shot up? 20 seconds? 60 seconds?
thanks

Posted by: rfinegan Feb 21 2022, 04:34 PM

...after about the 3rd crank at about 15 sec each. and getting nervous the pressure rose and swings right up to 70 psi

So bout 45 secs or so

cranking speed was fast and smooth too.

Better to alter the rod than the stubs.
You can flatten out the rod a bit with a hammer if the interference isn't too severe.
The actual shape of the rod makes no difference as long as the ends line up correctly.

Posted by: rfinegan Feb 23 2022, 06:05 AM

Thanks @http://www.914world.com/bbs2/index.php?showuser=209 I was hoping you would say that.. I will post back what I come up with. A little heat from the Oxygen Acetylene torch will change the shape in no time. But I will try a big hammer first. The metal may not be that hard. Every thing else seems to look and fits good and the little extra clearance on the clutch side make for a very clean clutch install with your remounted clutch pivot plate and some heat wrap. Looks very tidy.
Thanks again.. your the best and so are your parts

This is getting interesting...I think some on set the throttle pedal stop high to keep there kid from going to FAST!. ..

TIP: ALWAYS check Wide Open Throttle (WOT) when setting up your carbs or throttle plate.

MY stop on the pedal board took more that a few, to several turns to get WOT!

Heheheh..this is going to be FUN!

Now to hook up the ignition(Power) wires on coil and HIFIre/MSD then test fire and timing...

Take a look down the throttle bore HERE:

Working on the shifter clearance it from hitting the exhaust pipe. These are hollow and fairly easy to bend. I took @http://www.914world.com/bbs2/index.php?showuser=209 advice to maintain the locations of both ends by tracing a template of the Original shape on paper with a sharpie. Then off to the Vise to alter the shape and bend to fit. It took a few tries but I think I got it. Seem to get all the gears and does not touch . I will have to changes the Shift stops of the Rennshift, but that is not difficult at all. The white is just cheap primmer to show me where the rubbing was happening. Ill dust some black paint on it when I install the cover and boots after a test drive

Nice progress Robert. You will be driving that baby again in no time now. beerchug.gif

@http://www.914world.com/bbs2/index.php?showuser=9712 The Engine is running now ...working on the carb sync and timing . Set to an initial 8 degrees right now. A fresh 5 gals of 94 octane to get this thing up and going in the right direction
New parking cables and new dust boots on the pistons for the rear caliber are in progress along with the SS flex hoses from PMB group buy. Going to be nice to have Fresh brake fluid after how many years?

I need some help PLEASE.

I have the engine back in the car and its running poor and start the "SAME" howling noise I had just before it failed the first time. The engine turns over with the bolt on alternator fine so not thinking bearing.. or alternator?.

Please take moment and listen to this and let me know what you thing...note the head temp and oil pressure in video looks good. the first howling noise as while running and I stoped immediately. The next morning i pulled the plugs and compression check :
COLD WOT with charger
1 140
2 140
3 140
4 145

Lots of miss firing popping and fouled plugs
replaced plugs and set timing to 28 @ 3500 ( 8 base) running but not real well not missing and no power

It's been so much fun, lets do it again?
Since I did not find the root cause and just repaired the heads and valves, it no surprise that it failed again! It looks like it was not an over rev condition the caused the pistons to hit the pistons. I will only be posting the Fixes I encounter moving forward to keep the World Advised. IT is going to take a while as I am reluctant to shot gun more $$$ at this again.
I will install the original 2.0 and put her back on the road and have some fun...while I find out what went wrong? Thanks for the support and a big shout out for advice to @http://www.914world.com/bbs2/index.php?showuser=1095

Well that sucks, sorry don't have any suggestions.

Posted by: BeatNavy Mar 13 2022, 04:23 PM

I agree that sucks Robert. Are you sure it's something internal and not something intake or ignitiion related? When you tore it down last time you had evidence of valve interference. Were you getting the same symptoms last time? Those compression numbers look good, so....maybe NOT something internal.

Otherwise I have not clue but hope for the best.

Posted by: rfinegan Mar 13 2022, 04:33 PM

I'm going to do another compression test and maybe a leak down but somethings is amiss (pun intended ) ;-)

IM still hopeful as its not a catastrophic fail yet.. but the howling is seen on the first 15 min brake in and again on this build and can be heard on the video too. So internal seem likely..I will swap out he starter next as This was new to the 2056 on first start and ez to swap a Bosch in its place. Else its a bearing? I did reuse the bearings from first build as everything "LOOKED" ok and so were the journals

A howling sound might make me think something like gear noise. Could be as simple as a nick on either the cam gear(s) or the distributor drive gear(s). Best of luck

Is the howling noise the noise you re concerned about what we hear in the video BEFORE you turn the engine over and it sputters a little bit? The video you posted on the 12th?

If the key is in (I'm guessing it is as the head temps are reading) but the engine is off and something is howling, I'm thinking fuel pump. How is the fuel pressure at the engine?

To me it sounds like a dry bearing and pulls /slow the engine down till a stall. This is the sound it made just prior to my valves bending and pushrods (see first fail). Odd enough, returning the next day the sound was gone and only a miss fire on Cylider 2 (the popping was seen on cylinder one in video)
Currently it is running on 4 cylinders and no noise. I have done several leak downs and compression test. Still in the Diagnostic phase of figuring what the heck is going on. Ever day its something different and new symptoms
Fuel pump is under the hood and 2-3 psi. It is relayed with the key on via the power relay on the play board. Self regulating at the pump

Could it have been a tight thrust play? Maybe something ground it's way free enough to no longer cause noise, friction and resistance?
