New Air Oil Separator Leaks By
 

So about a week ago I replaced my AOS, upper hose, and bottom boot, with brand new parts from ECS Tuning. This weekend I took the intake plenums off to clean out the remaining oil, and I noticed the line that connects the AOS to the intake has oil in it. Shouldn't this be dry, or should I expect a little blow by oil here?

There will always be some oil residue in the line that connects to the intake.
