    Most positive crankcase ventilation systems have a valve known as the PCV valve. When does the PCV valve need to be replaced? Let’s take a closer look. The PCV system is seldom listed as a...

  6. Simple Guide to the Positive Crankcase Ventilation (PCV) Valve

    A PCV (positive crankcase ventilation) valve is part of the engine's breather system, and it helps to stop damaging pressure building up in the crankcase. This is A Good Thing, because when an engine burns fuel, a tiny amount of gases slip by the piston rings and into the crankcase.

  7. How Does a Positive Crankcase Ventilation (PCV) System Work?

    auto.howstuffworks.com/positive-crankcase-ventilation-system.htm

    A Positive Crankcase Ventilation (PCV) system regulates the vacuum pull through its crankcase. Once the vacuum gets higher than desired at idle, the PCV valve shuts off and stops that vacuum. The drop in vacuum leads to an increase in RPM, which in turn allows more gas to be pulled in.

  8. What Is a PCV Valve? - AutoZone

    The PCV (positive crankcase ventilation) valve is a crucial component of an internal combustion engine. It regulates the amount of air that flows into the engine's crankcase, which balances out the pressure and prevents harmful gases and fumes from escaping into the environment.

  9. PCV Valve: How Does It Work, Failure Signs, How To Test It

    The Positive Crankcase Ventilation (PCV) system operates by using a one-way valve, often located in the engine’s valve cover, to route gases from the crankcase to the intake manifold. As the engine runs, the intake manifold’s lower pressure creates a vacuum that opens the PCV valve.

  11. The PCV valve is a small one-way valve attached to your engine block, usually on the top or side of the valve cover. It uses a vacuum hose to pull unburned fuel and exhaust gases from the engine crankcase back into the intake manifold.
