04 DE engine question

Quick question, just wanted to see if anyone had encountered this before. I have a slight amount of oil in my intake manifold and inside of my TB, I have an ARC catch can and everything was clean when I installed it. There is no oil on the intake side of the TB and no oil in the intake pipe, any ideas where it can be coming from?

My guess is Its coming from your PVC hose connected from the bottom of your intake tube, may have been there before installing your catch can.

I thought it might be it. I installed the manifold, TB, catch can and intake together, all new and that is the only hose going to the intake. Thought maybe leaking valve seals, but how could it possibly travel all the way upstream to the TB?
