Ok maybe a noob question. I was installing a intake prototype for testing last night and noticed there was oil residue on the turbo inlet hose on the stock box along with a drop in the actual turbo inlet. This normal?

 

Yes, it's blowby from the PCV valve coming in through the nipple on the airbox. Most see a small bit, mine did it until it was broken in but haven't seen any more since 5k miles or so.

 

ill have to check mine out

 

I have noticed it on the top of my charge pipe where it 90's around the engine block but never none on the sri pipe.

 

My car has 31k on it. The oil is inside the intake pipe where it connects to the turbo inlet and a drop of oil In the inlet itself
