    Q:
    How to remove and install the PCV valve on Ford Edge? Posted by Customer
    A:
    For four-cylinder models, remove the intake manifold and oil vent separator bolts and gasket. Clean the engine block, install a new gasket. Reverse the process for installation, ensuring bolts are secure. For V6 models, remove engine cover fasteners, oil cap, and engine cover. On 3.5L and 3.7L models, remove the upper intake manifold. The PCV valve is on the valve cover. Turn it counterclockwise for removal. Replace the PCV valve each time it's removed. Ensure correct orientation when installing the new PCV valve. Incorrect installation requires replacement.

    Q:
    What is the purpose of the Positive Crankcase Ventilation (PCV) system and PCV Valve on 1993-2011 Ford Ranger? Posted by Customer
    A:
    The PCV system reduces hydrocarbon emission by scavenging crankcase vapors and circulating fresh air through the crankcase. It uses a PCV valve, fresh-air filtered inlet, and vacuum hoses to connect to the engine and EECS system. The PCV valve restricts flow during high intake manifold vacuum to maintain idle quality. In abnormal conditions, excess blow-by gases flow back into the air cleaner for combustion.

    Q:
    How does the PCV system work for the 2002 Ford Ranger? Posted by Customer
    A:
    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.
