I understand PCV valves allow varying degrees of vacuum depending on engine application. There is even an adjustable one. Someone with more knowledge than me will need to fill in some details, though. Also, I think Billy Nees just runs a vacuum brake booster check valve as a PCV. He will need to fill in the details.
