What is the purpose of the Positive Crankcase Ventilation (PCV) system and pcv valve on Lincoln Town Car?

Hydrocarbon emissions are reduced by the Positive Crankcase Ventilation (PCV) system which scavenges crankcase vapors, passes them through the air cleaner, and mixes them with blow-by gases before redirecting them back to the intake manifold through a PCV valve. The main components of the PCV system are, fresh air filtered inlet, vacuum hoses connecting these two components with the engine and EECS system, and PCV valve. The flow is restricted when there is high intake manifold vacuum so as to maintain idle quality, this is achieved by using PCV valve. When abnormal operating conditions occur, the system allows excessive amounts of blow-by gases to pass back into the air cleaner through the crankcase vent tube for normal combustion.

How to check PCV system and PCV Valve on Lincoln Town Car?

The PCV valve is in the valve cover. To maintain efficient operation of the PCV system check the PCV valve by starting the engine, disconnect the PCV hose from the air cleaner housing, and check for vacuum. Remove the valve and inspect the rubber grommet for damage. Also, inspect the hose for damage and ensure it fits snugly on the fittings.

Lincoln Town Car PCV Valve

The PCV Valve in Lincoln Town Car vehicles is yet a preserving device that assists in emissions control and boosting engine status. Located in the crankcase, the PCV Valve routes combustion byproduct gases back into the engine's combustion chambers eliminating both harm to the environment and the production of destructive engine-damaging oil sludge. Depending on the conditions of intake manifold vacuum, the PCV Valve controls the gas flow limited at idle speed to avoid lean burning while introducing more blow-by gasses at higher RPMs or load. Also, the PCV Valve helps to prevent the flame and assists the crankcase and piston rings to increase the compression that enhances power in the engine. It should be noted that timely service and checking of the PCV Valve plays a critical role in avoiding major expenditures because of massive destruction to a car's internal parts and in maintaining the efficiency of a car.

We provide a wide range of Lincoln Town Car PCV Valve at the best prices possible. If you need Lincoln Town Car 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 door step with a fast delivery service.
