Oil in air filter box - why?

Featured Replies

There is a bit of oil in my air filter box, where is it coming from and why and how do I stop it? I already replaced the pcv valve and didnt really help... Thanks guys.

did you clean out all the PCV hoses? I've seen some get really clogged, especially at the plastic 'T' piece.

Hm no I didnt do that.... thanks. Any other hose i should clean? Is the oil coming from the carb or just the hoses? Thanks.

Would the clogged PCV hoses have anything to do with me not passing emissions? :(
