How are you going to route your PVC valve?
I had mine just venting to the atmosphere for a while, and after a few hard runs under boost, I would notice that it would not really weep, but misting was kinda evident. Also around the oil dipstick showed signs of misting, but I've never blown the dipstick out of the tube. Then I ran it into an intake manifold port, and that worked OK as under boost the PVC valve would close. After a while, I ran the PVC back into the air inlet, upstream of the blower impeller using a mesh filter, and there's NO oil evidence anywhere the crankcase vents, even after mashing the throttle repeatedly. The impeller pulls everything out nicely when the boost falls off. Just trying different things in an effort to continually dress up the engine bay.
I was thinking of running it to the intake, but I will have to wait and see, never thought about running it to the upstream side,sounds like a good idea just so it has a filter on it
