The two valves were starting to get "sticky" Got real lucky, I was to pop them loose with a few light taps, applied some tranny fluid and they freed right up, neither push rod was bent. Set the valves & it ran like a new. [Reply]  [No Email]

May have bad valve. A piston ring issue would show up as blow by or oil consumption. [Reply]  [No Email]

THEN I would start thinking about things like stuck rings. [Reply]  [No Email]
