I wanted to update this with what I found. Well, it did the same **** all year, finally started to smoke a bit, only when warm.
I took of the carb and looked down the ports wit my borescope and found every single intake valve covered in black nasty coked up oil, on the back side and halfway up the stem . Shocked. Plugs still look like new.
Off come the heads. Inside headers are fairly clean and dry. Intake didn't appear to be sucking in oil.
I made a jig to put pressure into the intake side of heads and found all intakes leaking and also........get ready.....some sort of communication with intake and exhuast.. right where those big 2.08 intakes almost touch the exhaust valves. I believe there's some issue at the seats.
Whether this is my oil issue or not, I have no clue. My cylinders look like normal. Nice crosshatch still there.........I have to believe ANY ring problem would foul plugs, I hope.
I just hope that fixing up the heads and restricting oil to the heads can make everything right. My pushrods have an .080 hole.I don't think these old engines were designed to run with the valve seals submerged in oil.
Just another weird problem I seem to be fated for.
