    Q:
    What is the purpose of the Positive Crankcase Ventilation (PCV) system and PCV Valve on Ford Ranger? Posted by Wady R.
    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.
