What could the problem be?

i stand corrected, thanks, however you mentioned that i was only partially right on the dipstick info. could you elaborate? on my 87 non-turbo when i stepped on the gas my dipstick would shoot out 2 inches and it was the piston rings and i had to do a re-build. as far as oil pressure rise when you step on the gas. i have the normal rise on my 91 turbo now with just normal operation. on my 87 non-turbo it was riduculous. my pressure would peg out. that is the differance i was talking about.

Well i say that because if the dipstick was being pushed out, piston rings would not be the first thing to assume bad. There is a pcv system that evacuates excess pressure in the crankcase via the intake, and if this system is clogged, the pressure will have nowhere to go, and will push out the dipstick. Although if you have excessive blowby and the amount of blow by exceeds the amount of air the pcv system can flow, you will also push out the dipstick. Basically im trying to say don't assume the worst right off the bat, and start off easy.

You must have also had a clog in the PVC system or a MAJOR ring failure. I had a friend's old GM V8 blowing the hose off the breather system for the same reasons. But, an oil pressure spike is not a real good diagnosis of a ring problem, but a symptom of a major problem.
