Leaking oil - right before Mopars in the Park, too.

Just a thought,

Sounds like the PCV is somehow backwards. Flowing the wrong direction. When hooked up, it would allow the crankcase to vent to the carb from engine vaccume. It was probably always building up crankpressure when on the loud pedal.

That is unless I have always had mine installed backwards! Isnt it supposed to flow in one direction, from the crankcase to the carb?
