So it's Friday at 2:50 pm and I'm trying to find a PCV valve. Dealer is out and I'd have to wait until Monday, and all the local auto parts stores don't have a listing for an 06 4.7. I even gave them the OEM part number and still had no luck. Has anyone gone through this before and purchased one from Napa or AZ, etc. and have a part number handy I could give to them? Thanks guys.
