40,000 miles or so on the vf34. I have oil in my intercooler and throttle body. I cleaned it out yesterday and the oils back. Boost is low and if it does go up it's very slow. And last oil press is low by almost one bar from 6.2 down to 5.0 or so. I already have a catch can and that has nothing in it after 2 days, but the rest of the intake system is saturated.
