PCV Valve: Removal: 3.7L

The PCV valve is located on the oil filler tube. Two locating tabs are located on the side of the valve. These 2 tabs fit into a cam lock in the oil filler tube. An o-ring seals the valve to the filler tube.

  1. Disconnect PCV line/hose by disconnecting rubber hose at PCV valve fitting.
  2. Remove PCV valve at oil filler tube by rotating PCV valve downward (counter-clockwise) until locating tabs have been freed at cam lock. After tabs have cleared, pull valve straight out from filler tube. To prevent damage to PCV valve locating tabs, valve must be pointed downward for removal. Do not force valve from oil filler tube. 
  3. After valve is removed, check condition of valve o-ring.
