Frequently asked questions

What does the LR005991LR breather hose do?
The LR005991LR is the crankcase emission control breather hose for the 4.4L V8 AJ petrol engine. It vents crankcase gases back into the intake as part of the engine's emission control, with one hose fitted per vehicle.
Which vehicles does this breather hose fit?
This breather hose fits the Discovery 3, Range Rover L322 and Range Rover Sport L320 with the 4.4L V8 AJ petrol EFI (220kW) engine only, from VIN 7A000001. It doesn't fit diesel or other petrol engines, so confirm your engine.
Why do crankcase breather hoses fail?
Crankcase breather hoses typically harden and crack with age and heat, causing oil leaks, rough idle or a whistling vacuum leak. A split hose can trigger running faults, so replace it if the rubber is perished or weeping oil.
