I have oil in my throttle body. It's also inside the plenum.I have no idea where it's coming from. It's a first fuel injection set up, but it's really no different than a stock intake theoretically. I can't imagine it coming up through the runners and out in reverse flow of intake air. WTF.[ATTACH][/ATTACH]

 

Could be from the PCV valve?

 

I'm with DartByU That is common in high performance motors

 

so i should'nt be worried?

 

Is there a breather hose (not the one with the PCV, the other one that supplies fresh air into the engine) connected to the air filter plumbing between the air cleaner housing and TB? If so, a clogged PCV can cause the blow-by gasses to flow out through that hose instead of into the motor like it's supposed to, taking oil vapors with it.

 

no hose on the breather, it is a stand alone breather. I think it is the pcv. Do i replace it?

 

Pull it out of the valve cover and shake it. If it rattles it is ok, if it doesn't, it's junk. No more than 5$ at your local parts store...
