Actually, PCV stands for positive crankcase ventilation. From the name itself, you will have the idea as to what the primary functions of this part are. The purpose of this functional component is to effectively regulate the flow of the crankcase fumes into the intake manifold where they can be burned. Aside from the primary role that all PCV valves perform, it should be noted that the valve also has a secondary task, which is to serve as a check valve in order to prevent the flow from coming back into the crankcase. This set-up prevents potential ignition of the crankcase fumes the moment the engine backfires. Thanks to the special roles that the PCV valve plays in your Mazda, the performance of the engine is maximized. Because of the roles that the part plays in the system, it is imperative that proper attention be spent on it. Check the part if it is working in top condition. Most manufacturers recommend that the stock PCV valve be replaced approximately every 20000 miles or according to your Mazda's service schedule. Keep in mind that one crucial part of the PCV system operation is the positive seal, so it is also just right to check all the hoses, grommets, and clamps when servicing the valve. The moment you have a damaged valve, don't despair as replacing it is both easy and inexpensive. When that time comes, trust our site for your Mazda PCV valve needs.
