I finally did a compression test yesterday afternoon. The results
weren't pleasing. Each cylinder tested out around 60 lbs with throttle
wide open. I'm not sure what the norm is, but I know it should it least
be in the 120 -140 range. Does anyone know where I should start? I
have great oil pressure, 100 psi cold and 70-75 warm. The spark plugs
are fouling within about 5 or 10 miles of cleaning them. The deposit is
a dark black dry carbon buildup, telling me my carbs are running too
rich. The car has sat for about six years since I had new piston rings
installed by a local mechanic who I will never have work on my car
again. I have had people tell me the rings haven't seated yet. Someone
told me that if you take the oil fill cap of while idling and there is
air pressure coming out, the rings haven't seated. Anyway some advice
on what course to take would be much appreciated. Also my valve guides
are probably no good, I get exhaust smoke under heavy engine
downshifting. Is it time for a complete rebuild or Is there another
alternative?
Thanks in advance,
