    Q:
    How does the PCV system work for the 2000 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.

    Q:
    What happens in abnormal operating conditions for the 2003 Ford Ranger? Posted by Customer

    In abnormal operating conditions, the PCV system is designed to allow excessive amounts of blow-by gases to flow back through the crankcase vent tube into the air cleaner to be consumed by normal combustion.
