PCV valve delete?

You will sink your vacuum at idle, and pull all sorts of oil into the IM if you put in a check valve that flows too freely.

Thanks for the response man! I've got the OCC in place, so that would keep oil out of the IM. The check valve would be the one that Damond Motorsports provided with the OCC. So definitely less restrictive than the PCV valve.

I'm wondering if having the PCV valve out of the equation will pull a stronger vacuum on the crankcase during decel and throttle lift off to prevent oil from being pulled past the turbo seal when back pressure in the downpipe drops.

Do u have experience with this?

I'm planning on measuring crankcase pressure by hooking up my AEM digital boost gauge to a modified oil filler cap to see what difference a setup like this would make with vacuum on the crankcase.
