It's not something silly, like the
rings are on the pistons upside down?
Or low tension oil rings?
Or sucking oil from the intake via a vacuum leak? Are the intake gaskets oil wet at the bottom?
There's a limited number of places you can introduce oil into the cylinder above the piston.
Rings, valve seals, intake gaskets, vacuum line via carb from valve cover (pcv) or transmission...
If it's not sucking trans fluid via a vacuum line from the trans to the carb, and the intake gaskets aren't wet at the bottom, and it has new valve seals (which I don't run any and my junk don't smoke), then the only other way I can think of would be the
rings installed upside down.
I didnt even know you could put rings on upside down. I thought they could go any way. I learned something today. :lol: :lol:
