Looking for suggestions and a little help, I have been searching the web and trying everything to get my 370z to stop smoking. It only does this once its warmed up, the coolant temp has to be around 200+ and the intake temp is usually 90+.

My setup:
AAM twin turbos (running on 8psi)
AAM 3in true dual exhaust
Mishimoto 3 port catch can
Ecutek tune

I originally thought it was an issue with to much crank case pressure but I have completely removed the PCV valves on the car and hooked up a Mishimoto 3 port catch can. I have 1 port going to each valve cover and the out is vented to the air. I have also tried venting directly to the air thinking that the catch can was causing issues. The car never smoked on start up I always have to drive it for a while before it starts smoking and I really only notice the smoke when I come to a complete stop. I do notices an oily film in the exhaust and also there is a small amount of film in the intercooler piping coming off the turbos. The kit isn't very old I have only had it for 6 months and the car isn't that old either only a couple of years.
