    Q:
    What is the purpose of the Positive Crankcase Ventilation (PCV) system and pcv valve on Lincoln Town Car? Posted by Customer
    A:
    Hydrocarbon emissions are reduced by the Positive Crankcase Ventilation (PCV) system which scavenges crankcase vapors, passes them through the air cleaner, and mixes them with blow-by gases before redirecting them back to the intake manifold through a PCV valve. The main components of the PCV system are, fresh air filtered inlet, vacuum hoses connecting these two components with the engine and EECS system, and PCV valve. The flow is restricted when there is high intake manifold vacuum so as to maintain idle quality, this is achieved by using PCV valve. When abnormal operating conditions occur, the system allows excessive amounts of blow-by gases to pass back into the air cleaner through the crankcase vent tube for normal combustion.

    Q:
    How can you check the PCV valve itself for the 1981 Ford F-250? Posted by Customer
    A:
    The PCV valve can be checked by pulling it out of the rocker arm cover and shaking it. If it rattles, it can be reinstalled. If it doesn't rattle, it's likely clogged with deposits and should be replaced.

    What should be done if the valve is clogged for the 1992 Lincoln Mark VII? Posted by Customer
    A:
    The hose between the valve and the intake manifold should be removed and cleaned with solvent. After cleaning, the hose should be inspected for damage, wear, and deterioration. If necessary, a new PCV valve should be installed.
