What is the purpose of the Positive Crankcase Ventilation (PCV) system and PCV Valve on Ford Explorer Sport Trac?

The PCV system reduces emissions by scavenging crankcase vapors. Fresh air from the air cleaner mixes with blow-by gases in the crankcase and is rerouted through a PCV valve to the intake manifold. The system includes a replaceable valve, a ventilation filter, and connecting hoses. The valve restricts flow for idle quality. Excessive blow-by gases can flow back into the air cleaner for combustion. Checking and replacing the valve and filter is covered.
