Function and Common Applications

This PCV valve plays a critical role in the crankcase ventilation system by controlling the release of gases from the engine crankcase back into the intake manifold for combustion. It helps maintain engine efficiency and reduces harmful emissions.

• Prevents excessive pressure buildup in the crankcase
• Reduces oil leaks caused by crankcase pressure
• Helps maintain optimal engine performance and fuel efficiency
• Minimizes harmful hydrocarbon emissions
• Prevents contamination of engine oil by combustion gases

Installation Notes and Tips

When installing the Standard Ignition PCV Valve V297, ensure the hose connectors match the 1/4 inch (7 mm) hose size for a secure fit. The push-on attachment method requires firm pressure to seat the valve properly. Inspect the hoses for cracks or wear before installation to avoid leaks.
