Where is the PCV valve located on a 2002 Explorer Sport Trac?
This part runs along the top backside of the engine from one side to the other. It is a long black plastic piece that you can only get from the dealerships. Do not waste your time buying the PCV valve at an auto warehouse because it is NOT what you need. I cannot remember the cost but it was a bit pricey for what you get. If it is clogged though you will notice a huge difference... I know I did. $30 +/-
