Okay, so I pulled my intake apart this afternoon... Shaft play isn't overly bad, but it's definitely present. Gonna fabricate up a catch can, install it, clean the intake out and check the intake again in a few weeks and see if the oil is still present. My plan for upgrade (now I've researched it, I kinda wanna do it anyway) is to get Hypergear to highflow the turbo and install a NIStune daughter board to the ECU and tune it for 10psi boost. Should cost around $1700.
