What is the purpose of the Positive Crankcase Ventilation (PCV) system and PCV Valve on Ford Crown Victoria?

The Positive Crankcase Ventilation (PCV) system reduces emissions by circulating fresh air from the air cleaner through the crankcase, mixing with gases, and rerouting through a PCV valve to the intake manifold. The system includes a PCV valve, a fresh air inlet, and vacuum hoses. The PCV valve restricts flow to maintain idle quality. If anything odd occurs, the system allows excess gases to flow back into the air cleaner. It is required that regular checking and replacement of the PCV valve happens.

Ford Crown Victoria PCV Valve

PCV Valve is one of the significant parts of Ford Crown Victoria that plays an important role in emission control and engine performance. The PCV Valve safely burns the gases by recycling them from the crankcase back to the combustion chambers, thus helping to save the environment from pollution and destroying threatening oil sludge. Dependent on the intake manifold vacuum conditions, the PCV Valve limits gas flow at idle so that the engine does not encroach on a lean mixture, while at the same time, the valve is wide open with regard to the crankcase ventilation on full load. Also, it fulfills a flame arrester's role to keep the crankcase under negative pressure in the event of a fire outbreak. Failure to service the PCV Valve often exposes such familar complains as; contaminated engine oil, high fuel consumption, expensive repair jobs etc.

We provide a wide range of Ford Crown Victoria PCV Valve at the optimal prices. If you need Ford Crown Victoria PCV Valve, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your doorstep with a fast delivery service.
