    Q:
    What is the location and removal process of the PCV valve on Ford Mustang? Posted by Customer
    A:
    The PCV valve is located on the valve cover of 3.7L V6, 4.0L V6, and 5.0L V8 models. There is no actual PCV valve on 4.6L V8 models. If equipped, disconnect the PCV valve electrical connector. To remove the valve, just turn it counter clockwise while still connected to the PCV valve hose then remove the hose from the PCV valve itself. Return to Step 1 for installation procedures.
