Called two dealerships today to see if they had a pcv valve in stock. I was going to replace it just for preventative maintance. He tells me that it is only serviced with the valve cover. Yeah right like I'm going to purchase a new valve cover just to get a new pcv valve. Which makes no sense to me. Has anyone replaced their pcv yet? Ford was saying that the PCV is located on the driver's side valve cover. Other on this forums claim that it is on the passenger side valve cover. What is the deal?
