Went to a cars and coffee this morning with my friend, Rusty, who has FOUR 911's! One is a 1970 911S ground up restoration that is insured for $250K.

How did you degrease the engine without getting junk inside? Just spray and wipe with a rag? I have the same job to do, but no experience yet!

Bryan, I rotated the motor with the pistons pointed down on the side I was cleaning at the time. Placed a large cardboard box underneath, sprayed small areas and used a plastic putty knife and paper towels.

Doesn't matter too much if stuff gets inside though, it's all coming apart anyway. Just wanted it to be fairly clean before splitting the case.

That makes sense. I don't have a stand right now, but maybe I can pick one up shortly and clean it like you did. I wanted to pull the cylinders off and clean them up too, but wasn't planing to take anything else apart. (famous last words)

The motor actually ran pretty good considering what's wrong with it. It won't keep a valve adjustment ... meaning - I would adjust one side, then the other, but go back to the first side and the clearances changed. I suspect worn cam bearings, so it needs to come completely apart to mic everything. The ODO stopped at 108k miles and who knows when ... so a total refresh was in order.

You don't really need one, but having a good stand is much nicer

It's cooled off a bit so heading to the shop again this evening ...

Film at 11

EDIT:

Well, 11 came and went, and I didn't finish up until about 2am Sunday morning ... but in any event, here's what transpired:

Cleaned up the rest of the 1.7L case, using a heavy-duty foamy engine degreaser spray, a plastic putty knife and paper towels ... then an application of brake cleaner spray as a rinse

Next, I removed pistons 1, 2 & 4. I wasn't able to remove piston #3s wrist pin so this was pretty much the stopping point. Richard has a neat little device he made up for doing this task, so I'll be asking to borrow it, or to let me know how to make one for myself ... otherwise, I'm almost ready to split the case open.

So, with that out of the way, I moved back to the 912 motor to tackle the trapped head nuts issue. Was able to pound one of them CCW enough to get the Allen bit to grab ...

... so on to the other [more stubborn] one. I drilled a small hole through the length of the nut along the edge, then drove a wedge (old screwdriver) into the hole, attempting to spread the nut apart.

It still wasn't enough to allow me to turn it, so I'll have to drill another hole in another area. I think one 180° would be the best thing
...

I know the horror stories, but why not use an EZout?

Back on target...

I learned how to use the lathe yesterday... I now have bolts for my long studs... I'll finish them off down the road...

No pics, but removed most of the remaining tar from the floors... Seam sealer sucks!

Put another 16 miles on the LE's odometer today. Odometer now reads 48,583 original miles. The dreaded 50k is fast approaching!

It's a recessed barrel nut with an internal Allen head, Pat. The Allen bit tool striped out the nut when I attempted to remove it - the PO probably striped it when he torqued it on.

EZ-out won't work because the tip of the stud is less than a 1/4" below the surface of the nut - nothing to grab on to

Why worry about the mileage? Don't save your car for the next guy ... get out there and enjoy it. Cars are meant to be driven and I can't think of a car that's more fun to drive than a 914.

Woke up to this for the first time this morning

Yesterday I put in a side shift console with new seals, speedo drive with double seal, pulled both CV joints to put in new diff shaft seals, refilled the tranny with Swepco and took it for a drive.

The before picture was literally a foot square puddle of oil after I changed the old oil. Some of the seals I pulled were so dried out pieces snapped off them as pulled them out.

That's what my six is for The LE was my Dads car & has been a garage queen her whole life.

After being reminded on how to actually move the seats so I could get to the seatbelt bolts, I put in a new Sabelt 4-pt harness (passenger side is coming ... for now, I'm giving no rides). Found out that if using the newer eye-bolts (actually, I have to do this for this harness), when putting them into the tunnel, one should be careful if the bolts are much longer than the ones that were in there before (presumably stock) ... I ended up pushing against the shift linkage, making it impossible to shift. I also learned that when moving a seat forward, if you pull it out too far you'll need to find and press down a spring tab on the other rail (outside, or left leg) in order to get the seat to slide back in. That one baffled me for a while yesterday. Heheheh ... one thing leads to another! :roll eyes:

Now, back to tuning.

This took me a bit to see what you meant (or what I think you meant) since the plastic is so new and clear ... and that's kinda the point of any opinion I would have. I think it looks cool as hell, but if (when?) it gets scratched, it might be more annoying than a standard metal rain hat, no? I still think it's cool. I often want to take off the rain hats and filters and just let the ITBs shine and roar...

Had a few friends over yesterday for a little BBQ

Careful, a trip every weekend like that and you'll hit the big 50k in April 2017

my every day!

Put the Hot Start Relay kit on. Seems to be working fine. I hope it prevents me from having to replace my ignition switch again anytime soon. When the dumb ass current owner put the new (cheap replica) ignition switch in last year he bollocksed up the little screw that holds the switch in the cylinder. So he's not looking forward to sorting that out. Hopefully he won't have to

Got the relay kit from Pelly-can. Not sure if it's McMark's kit or not, but it was a very straightforward upgrade, so to all involved.

over the hill to San Gregario beach, and then down PCH to. Santa Cruz.

Only saw one or two 911s going up HWY1 from Monterey.

A nice day at the beach, too hot inland. 93 in Palo Alto.

nice view


Oh, I took the day off to spend some quality time with Dianne

I walked pass mine today...

Too much honey doo this weekend to drive...

Installed 914Rubber roll bar sail panels and top. Soldiered wires DAPO cut and spliced to
make horn work instead of buy a turn signal switch. Repaired seat belt plugs.

Amazingly, I put a muffler on my car and actually drove it around on the street a bit! I put a couple gallons of 100 octane in it and went for a loop around Cornell Road and Mulholland Highway near my house.

The muffler is a Triad 914-6 "quiet" version. It seems pretty nice and the car runs decently with it, although it's a race engine tuned for open pipes so is not completely happy putting around town. Honestly I can't hear the exhaust in my car at all because the carbs, fan and road noise are overwhelming. I also installed the new repro muffler support bracket I got to replace my broken Engman one. I painted it with stainless steel rattle can.

I realized about 3/4 way through the job that it would have been MUCH easier had I jacked-up the car. The bolts are very tough to access on the Triad.

The battery is dead again, i guess it's safe to say i need a new one ...

Woke up with what I hope is only a 24-hour bug - so didn't do much today

Later in the day Richard called and gave me some verbal instructions on how to fab a wrist-pin puller for cylinder #3. I rummaged through the junk pile and came up with this device:

Click to view attachment


Here's the Parts List:

(1) 7" length of 3/8" all thread
(2) 3/8" nuts (one is a locking/jam nut ... you can use a single Nylock if you have one handy)
(1) 5/16" flat washer (The OD of this washer needs to be smaller than the OD of the wrist-pin, but larger than the wrist-pin's ID, so it will grab the pin, but also pass through the rod bushing)
(1) 3" length of 1.5" diameter PVC pipe (I ground a 1/4" deep scallop into one end. This will butt up to the side of the piston and should prevent damage to the piston and/or the rings)
(1) 2" wide, 1/8" thick aluminum plate, with a 3/8" hole drilled in the center (I was lazy so I left the length of the plate long).
(1) 3/8" flat washer
(1) 3/8" all-thread coupling nut (a regular nut will work, this just happened to already be on the all-thread).


Theory of operation:

1. Remove the two nuts and flat washer from the tail end of the all-thread, insert the all-thread through the #3 wrist pin from the cylinder #4 side. Don't forget to remove both circlips first
2. Position the scalloped end of the PVC pipe against the #3 piston and reinstall the 5/16" flat washer and two nuts (snug them up and lightly jam them together - these take a 9/16" wrench).
3. Use a 1/2" or a 13mm ratchet type box wrench on the all-thread coupling nut. As you tighten up the coupling nut, it will pull the wrist-pin out of the piston and into the PVC pipe.

* EDIT - You may need to a insert a small screw driver between the wrist-pin bore and the doubled-nuts at the tail end, to keep the all-thread shaft from spinning when tightening the long all-thread coupling nut.

Unfortunately, I won't be able to test it out until tomorrow (if I feel better by then)

Masking off for final paint step, don't want overspray on a freshly painted trunk's.
72 All Stock.

That looks awesome!

Nice! The PO of my '73 had nothing masked when painting, and I have spent countless hours cleaning off over-spray.

Got a new battery and what do you know, she starts much easier now ...

Hey Andy! Did you check the condition of your alternator as well?

Nope, i'm pretty sure it's not the alternator.

I simply don't drive the car enough (less than 10 minute commute). I forgot to disconnect the battery over the winter and it drained completely. I was never able to get it to hold a good charge after that.

Btw., Optima replaced it under warranty free of charge!

You have that nice luggage rack, Andy ... if you put a small 5 watt solar panel on it, it would trickle charge your battery while you're at work (as long as it's in the sun)

Removed the front BUB to start body work. Man that was heavy. Would like to go with fiberglass replacement. Recommendations"

Made an aluminum side grille to match the aluminum GT style engine lid I'm building.

I did an AIR rear fiberglass bumper, local for us in L.A.
Lucky I have a shop so I could spend 3 days modifying it to fit (perfect accident free car)
You would think that they would include some custom rubber dogbones with the package...in order to fit their caddywhompus bumper.
Whatever co. that you decide to buy from, ask about their defect-return policy.
A-I-R supplies many mail order co.'s, so make sure you know where it's made.
There must be other/better sources out there.
Nice grille work by the way

Installed Sergio's GT lid.

Trying to decide where I want to put the Porsche lettering...kinda want to do something different than stock.

The wrist-pin puller worked great. I think I can shorten the PVC tube by an inch or more and cut down the all-thread's length too ... also going to get a Nylock nut for the tail end. Don't think I'm going to need this again for a while though.

While I was cleaning up the front of the case a little more (and preparing to pull the oil pump), couldn't help but notice this threaded plug. I'm going to take it as concrete evidence that this motor has been out of the car and worked on at some point after leaving the factory

Removed all the case nuts, through bolts and the oil pump, then inserted the case splitter ...

Rods have a little slop and the cam lobes have seen better days ... Cam drive gear looks great though.

I'll be running all the parts (along with a set of 911L P & Cs) up to EMW for a more thorough evaluation soon ...

Notice anything missing? ... there's no windage plate in here

Did early (71) 1.7L motors have them? (this is my first 1.7L autopsy)

Found a lot of gray metallic sludge on the inside of strainer plate too. This isn't a good sign

Oh well ... I cleaned the fuch out of it and gave it a fresh coat of hi-temp paint

That's all for now ...

Left rear wheel well was showing its 42 years on the road so I cleaned and painted it. Those runs are factory, not mine! Missed a few spots!

Stopped by the track just out driving and saw the Gainsco Red Dragon. They were fine tuning the driver. See the 914 roofline next to the 18 wheeler. And I got in a couple hours of driving in the country! Wahoo.

Company picnic today so I loaded up the rear trunk with two folding chairs, two beach towels, one umbrella, the picnic kit, and the all important thermos..

Off to Doheny Beach along the coast a couple of miles south from home (remember the Beach Boys Surfin USA lyrics)

Looks like the start of a perfect Saturday!!!!! Enjoy! I'm working noon to midnight! I know you're envious! Ha ha ha!

I spent 6 hours grinding welds trying to get the suspension ties off without damaging the outer suspension console. I got the little one off, but the bigger one is being stubborn. I was hoping to have them and the inner suspension console off today...

Installed a retro sound radio,914 rubber speaker pods and recovered seats. Click to view attachment Click to view attachment Click to view attachment

Looks great Moe!
