Farrar - I've never seen a PCV valve fail on it's own. I have had them plug up and stop operating, but a quick squirt of some brake cleaner frees them up so they work again. If a car has been sitting for some time, I could see where the PCV valve might glue itself closed on some residue. -- Mike -------------- Original message from Farrar <fhudkins@xxxxxxxxx>: -------------- > David, > > Now that's an interesting theory!
