- Regulates ventilation flow: Meters crankcase vapors from the engine back to the intake, its flow governed by manifold vacuum.
- Direct-fit replacement: Drops into the listed applications without modification.
- Emissions-system component: Part of the PCV circuit that routes blow-by gases through the intended path rather than venting them.
A PCV valve can stick open or clog over time. If a failed PCV valve is the cause, signs it may need replacing include rough or unstable idle, oil seepage from seals, or excess oil consumption — diagnose the underlying cause before replacing, since these symptoms can have other sources.
