I was wondering if anyone else is running a combined exhaust evacuation system and a PCV? I thought about this idea because the PCV works best at lower RPMs and the exhaust system works best at higher RPM's when the PCV fails, my main concern was the fact that PCV valves tend to leak, and at wide open throttle when manifold vacuum drops to zero, I was concerned mixture could be pulled into the exhaust. I fixed this issue with an aviation quality check valve, in line with manifold vacuum going to the PCV. I just built an oil separator to go with the factory one, to ensure all the garbage doesn't make it into the manifold.

I thought this might be an interesting discussion since the pcv only really works near idle
