Re: Oil in #8 exhaust port...rebuilt engine question
This is damn peculiar. Good insight from everyone. I think I will take another compression check on all cylinders. I have not checked the other plugs but I suspect they will look like the Ex ports , black and mildly sooty. I have not pulled the plug on #8 yet but when I do the C check it will be interesting to see if it too is fouled or coated in thick black engine oil. The dip stick shows the oil to be clear, which you would expect with only 1 hour of runtime.
I don't see any oil around the head bolt. That black spot on top of the one showing is the color of the ARP head bolt, not oil.
The engine got all new pistons, valve's, guides, rings, gaskets etc. It would be surprising if it turned out to be one of those. Block was magna fluxed for cracks and came back clean. The engine builder is a real pro and a perfectionist, which is why I chose him to do this rebuild. I sent him an email with these same pic's. Well see what he says.
One more thing, I ran my finger up the exhaust valve (gigity) and there was no oil on the valve, valve stem, or where it enters the casting of the head.
