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.

Ford Explorer Sport Trac PCV Valve

Combination throttle control PCV Valve in Ford Explorer Sport Trac vehicle is used in controlling emission and boosting performance of the vehicle. The PCV valve helps protect the environment and the engine itself from the buildup of dangerous oil sludge; it does so by directing crankcase combustion byproduct gases back into the Engine's combustion chamber. Depending on intake manifold vacuum conditions, the PCV Valve partially closes and does not allow much gas flow at idle but this can cause lean running of the engine; at higher RPM or under load the PCV Valve opens fully to allow increased blow-by gases. Also, the PCV Valve plays a role in a flame arrester and also helps in enhancing the compression of the engine. It is recommended that the PCV Valve should be checked and serviced on a regular basis in order to avoid some of the problems like contaminated engine oil, oil leakage, and high fuel consumption.
