I wasent sure if on the bottom of the s/c gasket was doing the same thing even though i used rtv...so basicly i thought oil may be comming though the pcv on the lim and going into the engine...it's a long shot but i cant imagine it being anything else....all i know that will make the engine smoke like that would be.....
worn piston oil ring
bad valve seals
Oil somehow getting into the intake
bad gaskets ect...
I can rule almost all of those out because almost all were changed. except the oil rings on the pistons. Wich it is not vary likely they just go bad all of a sudden as soon as i put the motor back together.
