When you find the pvc valve get some "Gunk Engine Cleaner" or other solvent and clean it out, if it freely "rattles" when you shake it, it is "good to go". Save yr money, times are getting tougher.

  • Hi, I can help.
  • Your PCV valve is located on the passenger side valve cover.
  • Check the hose to that runs from the PCV valve to the intake if you are looking for a leak. Them hoses rot a lot.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Trying to find PVC Value.


The PVC valve should be located on top of the oil cap near to the valve cover.
To remove the valve take off the protective plastic cover and undo the two small bolts that hold the falve using a 22mm wrench.
