Microsquirt can order today be here tomorrow most likely but still would not have time to break in the engine and sort out all of the potential bugs.

Too much money in it to not do it carefully and right.

I have a brand new Microsquirt unit in the box.
Come by and get it today.

Do it! You have the wiring complete.

Ohhhhhhhh man I have done exactly that. POP! smoke and dead Microsquirt!

The good news is that after I finished kicking myself is that there is a fuse on the board (IIRC) that can be replaced, and there is a guy in Virginia Beach that can fix it. He fixed mine.

Won't help get the car on the road this weekend, but its not the end of the world either.

Well after my last electrical failure I have been redoing all of the wiring!

Finally got to replacing the 12 pin wire harness that should have looked at least a little like this nice new one from 914 Rubber.

But after 44 years of time and some seriously questionable repairs it looked like this.

Was going to continue taking off all of the tape but when I found a wire nut and bare wires just twisted together I just had to quit!

Completely took apart Microsquirt harness and rewiring everything! Should have the wiring button up this weekend I hope.

I totally feel you pain on the wiring Mike. They are ready when they are ready, not when we are ready.
Looking forward to seeing your progress this weekend. Interested to see how much difference your tune will be on the new engine.

Mike,

What's the latest with Part II? Any progress?

So what happened??

Well after being sidelined by a long deployment to an undisclosed location I am getting it going. Finished all of the complete redo of the wiring and started it today! Oil leaks at the valve covers but other than than and resolving control of the cooling fan control moving forward. Pictures to follow.

welcome home! so that means we might see you driving again this year?(albeit in the rear view mirrior )

I've been gone so long I've been missing all these great build threads. Looks like a great combo!

There is one nice side effect of the coronavirus... Lots of old 914World members are wandering back in here. Because of boredom or masochism or maybe something worse.... Now we just need Miles to show back up.

Welcome back. We do miss you when you aren't here.

Well FUCK!

Got it started ran a few minutes. Decided to do quick oil change to get the potential debris out.

Dropped the strainer and found this!

For those of you that don’t know that is a retaining ring for the wrist pin! Photo is a bit misleading as it looks like lots of metal but it is actually just bits of sealant.

Stripped everything off will drop the engine tomorrow and hope there will s no real damage.

Ouch. That stings.

Hang in there, we're all behind you!

Man! That bites. What about going Teflon buttons instead?

Well I am one lucky SOB!

Looks like #1 lost the retaining clip but no damage to the cylinder. Minor scratches in cylinder but not detectable by touch. Also found #4 clip almost out.

Replacing all clips and putting back together. Take 2!

Well as I wait on my clips to be delivered I am getting to a few things I skipped in the rush to finish last time.

Installed the Tarrett Racing Semi-Solid trans mounts.

Talk about a dodged bullet!

Won't work with JE's.

Ok so maybe I am paranoid but this seems like a lot of crank movement and there is a a distinct clunk of things moving. I couldn’t make the code work for embedding the video so the liknk is posted below.

This is with the trans on did not notice this when I set the axial play but this just seems like a bad thing to have but I have no idea what is casing this.

Well hopefully I am a moron. Thought about it and this is happening with the valve train installed on one side. So of course it would move so much as it is loading only one side and the klunk is the valve springs pushing the crank forward and back.

Take your time with this and it will all work out.

That seems like too much Thrust play? Is the flywheel back on?

All good now! With only half the valve train in it moved a lot. Adding the both sides resulted in minimal movement.

While I did not pull the flywheel it now has what seems to be normal movement. Now just gives the expected small thunk when moving back and forth.

Whew!

Does anyone have experience with this tool?

Best tool in the world and worth every penny.

Yep. They are worth every penny of the cost. I was struggling trying to install the clips and was getting really afraid of damaging some very costly pistons.

This solved the issue quickly. Now I obviously had some operator error on my install. Resolved by installing pistons and clips before the jugs and using a ring compressor that came apart and allowed the pistons to be installed in the jugs from the bottom.

I have the 22mm one.

I will definitely order one before assembling another engine. Those JE circlips were really tuff on my thumbs, and had to have my son help as my thumbs were too sore to install all eight clips.

Taking it slow and easy as suggested. Did a final check of the intakes before moving forward and found a washer in the #1 intake. Always make a point to vacuum and inspect intakes with bore scope before adding the intakes.

Top part of engine done.

Love how the CFR exhaust looks!

Tomorrow add the Microsquirt wiring and start!

OK so long time no post.

Tomorrow enginge comes back out! I have an oil leak that I just can't trace down. Part of it is at the rear main but it is pouring out the 3 4 side. All I can think of is that I must have a leak at the cylinder case interface.

I did get in one small drive and this thing is going to be EVIL! Not a great tune in it but hit it hard from a start and smoked wheels all through first, broke wheels lose in 2nd and continued to smoke. Let off in 3rd but still smoked the tires.

Will pull it all down and reseal the cylinders and check all galley plugs and push tube seals. Had great oil pressure so don't think it is a galley plug but I am not taking chances.

New front and rear seal, new push tube seals, and seal up everything.

Well been laying low and hiding from the pandemic but do have a bit of an update.

Went through and replaced all seals including oil pump, tubes, front rear, oil filter, and new valve covers.

Fucker still leaks! Even with a bore scope I can’t see where it is leaking from. While I had it apart I did reseal some of the head bolts which seemed to slow it down some. But it is coming from the left front side from high up (yep checked the oil pressure gauge about 6 times and resealed).

I think it has to be coming from the are where the cylinders meets the block. This case was opened up for the 102s so maybe there is a flaw.

But as it is a slow drip (doesn’t seem to increase with engine speed/oil pressure) I have been able to drive it.

HOLY CRAP IS IT STRONG! Torque like I never felt in a 914 with a 4 cylinder. Rolling in second grear and you can spin the tire with a punch of the throttle. The Tangerine Racing headers and exhaust make a truly frightening noise. Obviously not too many miles on it but thought I would drive it a bit. Will take it to the dyno soon to see where it is and then start chasing the leak again.

Correction: The headers don't make that noise, your engine does. The exhaust system just doesn't stifle the awesome sound.

RE your oil leak: Have you checked the thermostat pulley bolt?

Other side of engine. But I did read one of your post that suggested that so I did check anyway.

Oh and by the way, I have to give Chris a shout-out for his oil cooler thermostat and cooler design. While not hot these days, this is a big engine and temps never ventured above 200 F. I have fan set at 190F so may be a bit of a delay in response but I drove it hard for a while and it was rock solid on temp. Had to take a bit of timing out to get cylinder head temps in the 250F range but cooling won’t be an issue for sure.

You can do it cheaper than CFR, but it will never be as dependable and as functional. Use Your Brain and use CFR stuff. I am a first class pain in the ass when it come to letting go of my dollars, but I have never regretted a single dollar I spent with CFR. Wish I was getting a discount for promoting CFR, but the best is worth paying for.

I have SOOOO been wondering how the engine was going. I am so happy you've been able to drive it a little bit. That kick in the back when you punch the throttle should be enough to keep you moving forward. Yeah, it sucks HARD that you're having all the problems - but once you've forced your way past them kicking and screaming..... dude..... it is SO freaking going to be worth it!



Dude... next Okteenerfest.... burnout competition between your and Clay's car in the parking lot?

It’s on!

I think I am a bit handicapped in this competition..... you don't have 245x45/16 tires on the rear.

But then again, I have 2 more cylinders and a bunch more displacement.

We need a burnout smiley....

It should be about even. But if not I have a Hollywood stunt trick we can use.

Despite oil leaks, I AM AN ENGINE BUILDING GOD!

Just look at the graph!

529 hp! It’s on the internet it has to be true? Right?

Well no, my tablet fell off the mount and it seems the accelerometers granted me a few extra hp.

Not sure how much I buy into the “calculated” hp, but this one seems close.

Click to view attachment

Am I reading that correct, 529hp?!?!?!?

Yes, but it was due to the tablet falling. The program uses accelerometers and gps to estimate hp. Obviously wrong.

DAMN!! With 529.5 HP, you had me sweating for a minute!

It was that final .5 hp that had me worried.......

Betty says that if you win our shootout I have to buy your drinks for the whole Okteenerfest weekend.


As for oil leaks, I am fighting them too. Good luck!
