What is a Crankcase Breather Valve?
The crankcase breather valve is a crucial component fitted inside the timing cover of your engine. Typically of the diaphragm type, this valve plays an essential role in managing the release of pressure build-up from the engine’s crankcase, ensuring optimal performance and longevity of the motor.
Signs You Might Need to Replace Your Breather Valve
Although the crankcase breather valve is a durable component, like any part subject to the rigors of engine operation, it may require attention. Here are a few indicators that it’s time to consider a replacement:
- Increased pressure in the crankcase leading to gasket failure
- Oil leaks around engine gaskets
- Poor engine performance
