still trying to diagnose a rich, wet, plug fowling right cylinder. whilst checking the air filter (which was wet looking and black as well) i noticed the crankcase ventilation system was leaking oil into the air mix. is this the function of the ventilation system? the very little i know about it, leads me to believe there should only be "blowby gasses" (clymers) and not oil. it seems oil in the air, thus in the carbs, thus in the heads is whats causing all of my current problems--- but have i just uncovered another???? please, how bad is this, and what needs to be done?
