Compression test results

[stefan]

I tested each cyl twice and this is what i got....

1 180, 175
2 205, 200 <-- #2 has oil on the plug and oil in the exhaust outlet
3 135, 140
4 150

check your seals your leaking somewhere . . . which would also explain the higher compression cause you cant compress liquid. Otherwise thats not bad for an older motor.

"2 205, 200 <-- #2 has oil on the plug and oil in the exhaust outlet "

Thats got to be either a valve stem seal, or perhaps a leaking head gasket between #2 and an oil passage? valve stem seals are cheap and easy to replace so i'd start there, otherwhise you may need to pull the head in which case you might as well toss some new rings on there which will probably bring your #3/4 compression numbers back up.

or you could keep driving it like it is (as long as you can get it past inspection?) and find a B6 to rebuild instead of rebuilding the stocker!

I had low compression on #3 and cleared it up with a chemical cleaner added to the oil just before changing.
I would imagine valve seals would tend to wear evenly on all cylinders unless there was something special going on.
The compression across all the cylinders should not vary by more than 5%.
