Aftermarket Part
Aftermarket: Quality alternative. This is a quality alternative, designed to fit and function like the original part, often at a more competitive price.
Crankcase Breather Valve for the crankcase ventilation system of the 4.4L V8 petrol and 4.2L supercharged V8 petrol engines. It regulates the flow of crankcase blow-by gases drawn from the engine back into the intake tract.

By metering these gases so they are recirculated and re-burned in the combustion chambers, the valve controls crankcase pressure and forms part of the engine's emission control. A failed valve can disturb the idle, raise oil consumption or create pressure-related oil leaks.

Frequently asked questions

What does the crankcase breather valve do?
The crankcase breather valve meters engine blow-by gases from the crankcase back into the intake so they're re-burned, controlling crankcase pressure and emissions. It's fitted to the 4.4L V8 petrol and 4.2L supercharged V8 petrol engines in the Discovery 3, Range Rover L322 and Range Rover Sport L320.
What are the signs the breather valve is failing?
A failing crankcase breather valve typically causes a rough or unstable idle, raised oil consumption, and pressure-related oil leaks around the engine seals. On the 4.4 and 4.2 V8 petrol engines these symptoms often point to the valve rather than the seals themselves.
Which vehicles does this breather valve fit?
This crankcase breather valve fits the 4.4L V8 petrol and 4.2L supercharged V8 petrol engines in the Discovery 3 (2005-2009), Range Rover L322 and Range Rover Sport L320. Confirm your engine is a V8 petrol using your VIN, as diesel models use a different system.
