I'm still running the Mr. Gasket setup. However, now it's on a supercharged 396. The header collectors provide an excellent vacuum source (via flutes), like previously mentioned.

 

Man the whole Crankcase Vent system is something that I am still pondering on, lol. Car is basically almost finshed (some Kooks, Spohn 4L80E Driveshaft, and Lonnies Duel intake pumps).
I have thought about doing the 1way check valve from each valvecover to the header but I was wondering if that would create any long term problems or if it was more feasible on a track car than a Daily Driver??

I was personally thinking of plugging the valvecovers (no filters) and running a -10 line from the PCV on the intake with a 1 way checkvalve and and a oil/air seperator to the suckside of the blower (self contained D1SC)? This way as RPM increases the blower would pull crankcase(just like the exhaust idea).
