If there's not a check valve on the PCV line it might be a good idea to get one. Could have too much oil pressure to the turbo. What size supply and return lines did you run? where did you tap for the supply and return? Make sure all the V-bands and connections are good and sealed.

not sure what size the supply is but its small. its the stuff included in the tp stage 2 kit. the return looks like its a #6 or 8 AN fitting sizt. its tapped for the supply right above the oil filter and the return is on the very front top side of the pan.

You need at least -10 or -12 drain line. Or 5/8 to 3/4... whatever

I had the same "smoke" problem and I had -12AN drains I ended up using nitrous jets as restrictors to finally get mine to quit. This was on my old GTO in my sig.

Feed line is a -3an, and the drain is -10an. The fitting at the turbo is
1/2npt x 10an, the one at the pan is 3/8 npt x 10an.
The hose fitting at the turbo needs to be the straight one and the angle one goes at the pan.

Smoking can be cause by lots of things, drain angle, oil psi, oil line not being straight as possible with no kinks.. With a drain issue you will have a smoke machine out the exhaust tail pipe. Only when lifting or under boost would be more like a vacuum line check valve thing. If the smoke is white thats water, oil will be blue and smell like oil..

have you installed the check valve in the rear pcv line yet and vented the front passenger cover?
