Your Ford vehicle is equipped with a Ford PCV valve which is one of the emission control components. Gases and vapors are the byproducts of your vehicle's internal combustion process. Now, the PCV valve is responsible for maintaining the constant pressure within the engine's block through releasing oil fumes when they reached a certain pressure and send them to the fuel system to be re-combusted again. In other words, the PCV valve is the one that routes unburned crankcase exhaust gases back into the intake manifold where they can be combusted again. Through the efficient function of the PCV valve, the life of your vehicle's oil and engine is prolonged. It also prevents the condensation buildup and burn fuel fumes that get by the rings. The condensation buildup can create sludge that causes the blockage of oil galleries and return holes and once they are blocked, it results to engine oil dry. But also note that an incorrect design of the PCV valve would blow out the seals and gaskets located inside your vehicle's engine. Now, to make sure that your Ford PCV valve will carry out its function efficiently, meaning without failure, you need to keep it always at its best. Yes, always do your part - perform your car maintenance and include your Ford PCV valve when you do it. Check for any signs of damage. It is recommended that the PCV valve and the filter must be replaced at every 30,000 to 50,000 miles as stated in the vehicle's manual for service interval.
