niceasssupercrw: you are referring to the heating tube by the throttle assembly? I took it out and cleaned it, tested the resistance and it only showed 12 ohms... seems pretty low for a heater. perhaps thats the problem. I dont know if these have a pcv "valve" inside the manifold or just a pcv system.. and yes, the o-ring seems intact enough. It is certainly a pressure problem because when running and warm, I pull the dipstick and there is definatly smoke puffing up. same with the oil filler cap removed.

With smoke coming out like that, it sounds a lot like blow by. Which could be a PCV problem, or something more serious. Does it run okay otherwise?
