Getting ready to pull heads

I could be wrong but, back in high school auto class, many years back, I was told add oil to the cylinder and if your compression goes up, it is your rings.Not sure if this will help in your situation ,but I would give it a try.

You are right but adding oil to a cylinder will always make the compression on a good cylinder rise. It's when it doesn't rise there's a problem. Plus if you don't clear the oil out afterwards it has the strong potential for make a REALLY loud noise when you fire it up. It's called hydro locking.

When i tested the thing (dry) ALL 8 were between 215 and 220 crazy consistent...I have a leak down tester but thats checking a closed combustion chamber for leakage-More specifically the LOCATION of the leakage, usually after a bad compression test no?

The other think is that is doesnt smoke except for a puff when going suddenly WFO from cruise, but i attribute that to the sudden shot of gas?
