pulled intake yest and no oil or much residue if at all on the tb, did a compression test, all tested each twice and across the board i got 216-219psi...no more then 3 psi variance between cyl, although when i pulled the plugs i found oil had pushed up around the threads and had some on where the plug seats...and you could def tell by looking at the cyl head its been burning (black ontop). Top of spark plugs was grayish white
im thinking leak down, as this would give full compression still, but leg oil leak onto the valves and into the cyl while keeping compression
but my thought is that wouldnt effect oil pressure ya?? cause that would come from right under the vavle cover, by the cams??? and that area is actually under a bit of a vaccum cause of the vent to the intake??? or am i incorrect there...
anywho...thats what im thinking cause if it were piston rings i should show low compression and i dont, and really only other 2 things are pushing oil into intake (not happening) or past valve seals...
