Never done it. I think it's just a little plastic thing that screws in place. Honestly, I think changing the PCV valve is more corrective maintenance than it is preventative. But I'm no expert. I gladly defer to anyone who knows more about it than I do.
Look for a rubber hose coming from your intake tubing or stock air box. It should be your PCV line. Trace it back to the engine and you should find your PCV valve.
