Okay. Here is a dubious one. I have low compression in at least 3 (I think maybe all 4) cylinders. It's been a while since I did my last compression test--my car's been off the road for 9 months. The compression which was normally 200-220 psi last read 140-160 psi. The car will not stay running without some careful gas/brake/clutch finessing. There is no smoke emanating from the exhaust, coolant level is fine/doesn't appear oily. I thought perhaps a camshaft or both had slipped or timing belt jumped, so I adjusted the camshafts and set them back in place, that wasn't the problem. I eliminated valve seals/valves and headgasket as the problem. I've never seen more than one piston ring go at once, so I kind of don't think that is the problem. Otherwise it would be pushing oil up into the head and through the crankcase breather to the intake. And the intake is clean. Hopefully you guys can give me some helpful insight as to the problem.I have a breaker bar and a free weekend so I may end up taking the head off if nothing else.
