You could have a bad oil ring on the piston or when he installed the rings, he put them on wrong. If you install the rings the wrong way, you can have oil leak into the cylinder.

ORIGINAL: jroseman

i did a compression test and the numbers range from 155 to 140 with the #1 cylinder being 145. The lowest cylinder is #8 with 140. I did not do the compression test with the oil squirt and retest.
If it is not the rings in the #1, where could the oil be coming from to make just that cylinder's plug so black. As i said, it has not fouled yet.

If there was some way i could determine it was not the rings and in the heads, I would buy some new neads. The current head are stock except for porting and roller rockers.
I don't know if I have new valves. I know I should know but I don't. If I pull the heads, how can i tell if the valve guides are shot?

I don't want to buy new heads if their are deeper problems.

I've decided to pull the heads and take them to a good head man - to check the guides and seals. I would have to do that anyway to check the cylinder and rings. Guess I'll start tonight unless one of you more experienced guys can give me a reason not to. thanks, joe

Good place to start, you would need to do that anyway in order to do the ring repair.. I think you're going to find you have a bad oil ring or improperly installed oil ring.

If you are not going to take it back to the original mechanic and demand he fix it, that sounds like a good plan. Me, I would raise holy hell with the mechanic.

With my old mechanic, I'm just tired of messin' with him. Besides, I want to learn all this stuff myself. No better way to learn than to do it.

I just pulled my carb and found oil dropplets on the base. Also, there is oil stain in both the intake runners under the carb. Going back to pull the intake off and see what I can see. I will keep you guys posted. Thanks for your advice and encouragement...I don't feel alone. Joe
