Hey Guys:
This belief that you need a PCV to relieve crankcase pressure makes no sense to me. I find it hard to believe that a breather cap on each valve cover cannot relieve what pressure might build. Cars ran for decades without PCVs and did not explode from crankcase pressure. How much blowby are some Cobra owners getting?

The PCV was invented to burn off spent gasses not to relieve pressure. Just my 2 cents worth.
