I’m about to take the IM off my 95k S8, to address an oil leak that I hope is the oil filter housing o rings.
I guess it’s still got it’s original PCV fitted, which to my knowledge is working ok. Can you successfully clean it to ensure it works properly, if so how?
Or do you just replace it?, I have also seen some posts on other forums to stick with the OE part when replaceing vs the cheaper Vaico part.
Any thoughts?
