For those concerned about too much vacuum, we also have a vacuum relief valve. The whole system needs to be looked at in the two primary scenarios; idle/low throttle conditions and WOT/boosted conditions. There are many ways to skin the cat, just depends on your goals.
A solution to remove the factory PCV but not by replacing the entire valve cover. Where would the relief valve go? In line with an OCC?
