Thanks for the reply.
A friend of mine (a lot better mechanic than I) was thinking along those lines too I guess. He fabricated a oil fill cap that "breathes) by
Cutting out the cap and added a piece of porous material in hopes that the engine just needs to breathe more. There is no pvc.

And yes, normally the lift runs for short periods of time almost every day ( around 15 minutes or so)...

Thanks again
