Positive crankcase ventilation

Bewy said
For low vac cams that will not operate correctly with the stock PCV, I just modify the stock PCV. I am only worried about the flow at idle. That flow area is about the size of a 7/64" hole. I gut the PCV, braze/weld in a steel disc, then drill a 7/64"hole in it. Job done & I have done many.

I run a fixed orifice (small ID hose inserted into a gutted PCV body) along with a Moroso oil separator for my system. Even with well designed valve cover baffles I still get some oil drawn through but at least the engine ain’t sucking most of it in, just drawing in the blow by gases like the PCV setup is supposed to.:thumbsup:
