I don't have it anymore But when I was doing my brakes I had a booklet that came with the little mightyvac style handpump (Equus) for Vacuum. In it there's a section for testing egr and pcv valves. One could always do an "as found" test to determine what their own PCV opens at? The ones I have seen don't have any spring to lift against, I think its their actual valve weight that determines the vaccum required to open the port. The body is lifted up off the seat at peak vacuum thru the suction in the line to the intake/carb

So having said that, could a guy simply look at that great wall full of PCV valves and pick an application with lighter/less vac setting??

Lastly how about adjusting the air/fuel idle adjustment screws with a vac gauge at idle, looking for that optimum amount of vacuum? As you guys say you may only get what you get due to a wilder cam. Then your stuck.
