What's involved
What this repair actually is.
The PCV valve vents pressure and fuel vapors out of the engine's crankcase and back into the intake to be burned cleanly. When it clogs or sticks, pressure builds and pushes oil past gaskets and seals. We replace the valve and check the connected hoses.
Symptoms
How you can tell.
- Whistling or hissing from the engine
- Burning oil or oil disappearing between changes
- New oil leaks from multiple gaskets
- Rough idle or check engine light
- Sludge under the oil cap
If you delay
A stuck PCV valve builds crankcase pressure that blows out gaskets and seals, turning a cheap valve into several expensive leaks.
