Warehouse find - 87 Engine and partial torque tube
#48
Hmmm a few years ago I bought a 1987 S4 engine with all the hoses, alternator, ac compressor, and engine harness for 2k delivered. It has 106k on it, and I saw the video of it running before it was pulled. I have it as a spare for my 91 when I pull it to do a complete rebuild.

First road trip was to Frenzy. Performed well on the way up. Not so much on the way back. Definitely spark related.
Checked the plugs and this was what I found #8:
Verified spark.
Cleaned it and took it for a test drive. Pulled it again and it smelled of oil.
Knowing the condition of the bores I believe the rings are stuck.
Plan is dump a cup of Berryman B-12 or MMO in the spark plug hole, leave it in there overnight, suck out what is left and blow out the rest.

So, last night I poured a cup or so of B-12 in the #8 cylinder. It was at the top of it's stroke so I ended up with liquid up to a bit below the edge of where the head meets the cam cover. I also poured a bit into the open cylinder of an 89 block with no known issues.
Fast forward to this morning...
Went to see if the fluid in the 89 dropped and it was at the same level it was last night.
Checked the #8 hole and the level had dropped to just inside the spark plug hole.
Hopefully, the B-12 is doing it's job.

Kevin, sorry to hear you're having issues; I hope your solution works.
Whenever I get an engine, I'll strip it down to the shortblock and clean the piston-tops and carbon-track at the top of the cylinder using carb-cleaner and a piece of wood, carefully.
I'll also use mineral spirits and create a puddle on the piston-tops and let that soak at least overnight. I'll tip that bank downwards and rotate the crank back and forth, and bits of carbon comes running down from the sides of the pistons. I'll repeat until no more carbon bits.
Also, I'll have the heads rebuilt with new valve guides, replace front/rear crank seals, etc., etc. as well as take a peek at 2/6 bearings.
Did you do a compression test after finding the oily plug? Let's say the numbers were good, then that would imply the valve guides are worn if they weren't replaced, and the source of the oil ingestion.

It's all good. You take your chances and sometimes this happens.
I have all my heads rebuilt before I use them. This one was no exception. Next time I'll adjust my process. :-)
This car has a 6.0 stroker in it's future, so it was never a long term use for me.
This is what makes ownership so much fun. I learn a bunch along the way.

Down on power - getting up to speed, slowing down at constant throttle up hills.
It was fun building speed downhill to maintain it uphill. Spent more time in the far right lane then I'm used to.
I still could get up to 80+ MPH and play with other Porsche's and corvettes. :-)
Remarkably, I still got 20 MPG on the way home.

Sucked out the B-12, blew out the cylinder with compressed air and took it to a drive. Drove horribly. No power and popping in the exhaust.
Nurse it home and swap the spark plug wire to the same cylinder and it ran much better. Took it for a test drive, pulled the plug and it's dark, but no oil smell.
I'll keep an eye on it and check after I put more miles on it.
I will note that when I checked the B-12 level this afternoon it had not dropped much if at all. Still about at the inside of the spark plug hole. Either the ring loosened or the level of the B-12 dropped below the ring that was leaking.
