FWIW, I have never had any luck with those billet PCV valves, even on cars that don't get driven in anger.
Instead of buying another billet thing to gut and ending up with just a 3/8" line on the clean side to the air cleaner, grab one of these with a 5/8" nipple.
The 5/8" will keep your engine will keep your crankcase from going positive pressure in most cases.
