So, you cracked the seal on a factory head gasket? That is a nice looking cam sprocket. I'd probably put it back in and run it another 20-30k miles. Chain stretched out? The cam and lifters probably look new too. Too bad that shop tried to get one over. You gotta have the valves closed to get a good leakdown. I was gonna ask if they squirted some oil in ans checked it again.

At least you are in good hands at Steve's.

The engine looked great. I bet I could have had the turbo fixed and ran it another year or two. I'm trying not to judge the engine shop too hastily. They have an excellent reputation locally. But I did get a sheet that showed 90% leakdown in cylinder two into the crank-case. I don't think they were trying to pull anything but perhaps had an inexperienced tech?

No harm no foul though. Glad that Steve offered his services before I took the car to them.

As far as the leakdown goes, as was not there and can not say.

Bison did point out the compression leakage on the center cyls of the heads. And after tearing down your turbo he does not suspect it was the source of the smoke. Where does that leave us? At this point it is a moot point as all of it is at the machine shop. Valve stem heights where all over the place so my bet is it was a valve leaking. You did say your compression test was good.

You can bet when I get it back together it will be right.

Got a few bent rods or out of round crank throws looking at them bigend bearings with wear on one side

I had to have my rods straightened when I did a minor rebuild. All 6 were bent and 4 were worse than the other 2. Machine dude said many are tweaked from the factory but good enough to work well; until you throw some preignition in there . Anyway, straightened stock rods have 50+ passes and 20k miles on them. Amazing what stock stuff will hold up to.

No exhaust residue? I've seen where the coating was cracked before and not actually leaking. I can't tell from the inside pic but apparently that's why you posted it as well.

Where in Virginia you guys from? I'm in Radford and go to Motor Mile Dragway quite a bit.

Oh no you can see light through it, cracked quite bad.

 

[TurboBuRick]

Roger that. You gonna weld them up?

Im in lynchburg but would definitely make the trip to motor mile. Been wanting to hit up Richmond Dragway TnT's for a while.

Rick, my o2's were swinging around all over the place. I think this might have been the cause of it. Me and Steve realized we are both having a weird tuning issue last time I was up there. Sometimes I'll be driving and feel a miss. The CEL comes on briefly but no codes are thrown. Ever heard of this? Steve has tried everything to get rid of it.

Sounds like a bad chip connection or possibly bad chip. First I would remove both chips and check for corrosion. Retention the contacts and re install.

Also good to cycle the plugs on the tpro once and a while. Not the best connector plugs.

Yes sir. New headers are expensive.

Sounds exactly like my issue. I just bought a new wiring harness. Will be a while before I install.

Dont forget the chip will go back to defaults as well.

Here's a little update. Parts are out of the shop. I started playing with rod bearings tonite. I am mixing standards and .001's. Here are some random pics.

 

[Steve V]

Couple items of note. I have saved all the orginal rod bearings. Measured them for thickness as well as bearing clearence. Most where .0027-.003 engine was quiet and oil pressure was 25 at hot idle. I won't get a chance to set up the mains until Saturday.

 

[m3x1c0]

looks bangin! such a clean shop too! Cant wait to fire it up!

 

[Steve V]

Rod and mains all set up. Rod 2.2490 clearences .0017-.0022. Mains 2.4986 clearences .0022-.0018 mixing and matching stds and .001's. Rods all stds. Bearing roulette is over now I can begin the assembling.
