Default Need some help

This morning I decided to put my air intake back on and when I took the elbow I found oil in front of my tb plates. Car has been running fine and no codes have been thrown. Is this normal?

Normal, and usually due to it coming from the VC vent line on the passside that connects to the TB. Check your PC valve (on dr side) to make sure it's not clogged and are are getting crank case pressure. Some guys add a catch can to keep this from happening as I bet the inside of your intake looks nasty.

Ok so with the catch can that will eliminate the hose coming from the passenger side valve cover to the throttle body.
