I have a 2005 STX with the 4.6 Liter engine and I want to replace the PCV valve but no one has them. Everywhere I go "Advance", "Auto Zone" and a few local places say N/A not available. I know it has a PCV valve. Any body know why this is? I suppose I could stop at the stealership, but would rather not.

 

The dealership would be your best option. There have been a number of threads on this for both the V8 engine choices. Common consensus is that yes, in fact, it does have one but it is not a normally serviced component.

 

10-4 thanks Lenn
