    Q:
    What should you check if no vacuum is felt when the PCV hose is disconnected for the 2000 Ford Ranger? Posted by Customer
    A:
    If no vacuum is felt, check for vacuum leaks at the valve, filler cap, and all hoses. The oil filler cap, hoses, or valve cover gasket may be leaking, or the PCV valve may be bad.

    Q:
    How does the PCV system work for the 2000 Ford Ranger? Posted by Customer

    The PCV system works by circulating fresh air from the air cleaner through the crankcase, where it mixes with blow-by gases. It then reroutes this mixture through a PCV valve to the intake manifold.
