Ok im continuing this from an aborted fuel injector thread. Thatll be postponed for a while i guess.
This is an 87 turbo, about 215000 miles.
These are the results of my compression test:
6 - 10psi dry / 30psi wet
5 - 10psi dry / 30psi wet
4 - 160psi dry
3 - 170psi dry
2 - 180psi dry
1 - 160psi dry
So from this im thinking straightaway it must be a leaking HG between #5/#6.
The even rise in psi after adding 2 capfuls of oil to them tells me the valves must be all good. But i guess it could possibly be bad piston rings, but just 2 out of 6 rings? And adjacent piston rings at that?
As for the high readings for #2/#3, maybe just carbon deposits i think. Not too worried about those, i would kill to have compression that high on #5/#6.
But the headgasket was replaced just before i bought the car about 4 years ago, or so i was led to believe. They showed me the reciept from the machine shop for resurfacing the head.
So, does anyone have any input here?
