Aftermarket PCV valves are a crap-shoot. They may or may not open. If they don't open, then the vapor will go out thru the breather and you'll have oil in the breather and oil over the motor. I replaced the PCV valve with a disc with a 1/16" hole, so the motor is always sucking the vapor. Some cars use this and they call it "calibrated orifice", fancy name for a hole.
