hard to explain. I know I sound like a n00b
normal, it's just some oil mist and water condensation.

It's only after it sits warm so I have no idea... Guidance please! Pretty embarrassing I might add.... Add that to the list of silly things to be embarrassed about.. Like uh wastegate rattle.

Thanks for the clarification on that. It was freaking me out!

So I plan to remove the valve cover and look at the PCV channels. Is there any way I can just clean the gunk out? Or do I have to buy a whole new valve cover..??


I'm hoping the PCV system is clogged and its causing positive pressure in the oil system thus pushing oil out of my turbo seals.

But the more I read about these RB turbos it seems like a lot of people experience blown seals right around 30,000 miles.
