Re: oil in cylinder
Hmmmmm . . . if you have the typical 3-piece oil ring setup (2 rails and an expander), they can't go in backwards - there is no orientation. You didn't happen to check the compression before you pulled the heads did yah? I'd want to know if that cylinder was holding compression the same as the others. If the oil isn't coming by the rings, then the next obvious place is through the intake guide. It looks like it is the rear cylinder, so I'm wondering if your engine has the oil baffles installed in the valley area? Maybe you're throwing a lot of oil up into the valley - and a "loose" guide or one with no seals on it is pulling oil into the cylinder? What type of crankcase breather system are you running? Is it a stock 49-53 setup with the oil draft tube . . . or???? Just some things to think about . . .
