PCV on PD blowers

I thought I would bump this thread up since what I have come up with for my truck pertains directly to PD blowers. See the diagram below for diagrams and airflow in idle and wot states. How the system acts in between will depend on the cracking pressure of the check valve and MAP state.
I currently have the vented catch can installed with -10 from the pass cover and connected to the stock pcv valve with 3/8" hose on the driver side. Once I find a 5/8" inline check valve with low cracking pressure, I will pull the blower off and finish the driver side with the -10 and 3/8" hose to blower inlet. As it sits now, I still get fumes at idle but it no longer blows oil out of the filter onto my headers.
