I was looking for a pcv valve that is threaded on both ends, so I can run AN line directly to it. Unfortunately my search has yielded me nothing... Now, there are check valves available in the configuration I need. The question is, what's the difference between our stock pcv valve and a check valve with say a .3psi crack pressure? Is there any reason I can't run them in place of the PCV valves?
