Manage crankcase pressure and route blow-by gases along their intended path with the SKP Engine Crankcase Vent Valve SK450366. It drops in as a direct-fit replacement for the 1998-2003 Volkswagen Beetle, 1999-2004 Volkswagen Golf, and 1999-2004 Volkswagen Jetta.
- Crankcase ventilation: Regulates the flow of blow-by gases out of the crankcase and toward the intake, helping keep pressure controlled inside the engine.
- One-way control: Meters the vapors drawn under intake vacuum so the crankcase can vent through the designed route.
- Direct replacement: Designed to install in place of the original vent valve on the listed Volkswagen applications.
Over time a crankcase vent valve can stick, clog, or leak. If a failed vent valve is the cause of oil leaks at seals or gaskets, rough idle, or excess crankcase pressure on your vehicle, this part replaces it — diagnose the underlying cause before replacing, since these symptoms can have other sources.
