What is a PCV valve? And do you really need to change it? The PCV (positive crankcase ventilation) valve is a one-way valve that recylces crankcase gases back into the engine burn. The PCV system is seldom listed as a maintenance item, but an old valve that is no longer functioning like it should can cause performance and emission problems. The PCV valve routes air and fuel from the crankcase back through the intake manifold to the cylinders rather than allowing them to escape into the atmosphere. If the valve doesn't open and close on a schedule, or if any part of the system clogs, the result can be sluggish acceleration or increased oil consumption. If you have a bad PCV valve, PCV valve replacement could eliminate the problems listed above.
That's why you should have your PCV valve changed or at least checked every 60,000 miles or every four years, here's some ways to tell if you need your PCV valve replaced:
When removed and shaken it doesn't rattle
The valve is stuck open
You can't feel suction coming from the valve hose
It doesn't click when removed from its housing
Over time PCV valves become plugged, clogged, and dirty resulting in major problems with your vehicle. These problems can range from a rough vehicle idle, poor mileage, or even oil leaks.
