haha ok. sooo your hypothesis is its either... piston rings, PCV valve, turbo, valve cover gaskets (which wouldnt cause it to come from the exhaust) cam seals, or "something like that". haha. so...this is right where i was. instead of just throwing parts at it, id like to find the origin and fix that. maybe a AOS would be something good in the future but right now i have a bigger problem.
