Crankcase Breather Cover - part of the crankcase ventilation assembly on the 3.0L Ingenium AJ20P6 six-cylinder petrol engine.

The cover closes the crankcase vent valve housing, sealing the chamber in which oil mist is separated from blow-by gases before they are drawn back into the intake tract.

A distorted, cracked or oil-weeping cover compromises that seal and disturbs crankcase depression. Once the mating face is damaged the cover is replaced rather than re-sealed.

Frequently asked questions

What is the LR181446 crankcase breather cover and what does it do?
The LR181446 is a crankcase breather cover for the 3.0L Ingenium petrol engine (AJ20P6). It seals part of the crankcase ventilation system, routing blow-by gases back into the intake and keeping crankcase pressure controlled on these Land Rover petrol engines.
Which vehicles does this breather cover fit?
This crankcase breather cover fits the 3.0L AJ20P6 petrol engine in the Discovery 5, New Defender L663, New Range Rover L460, Range Rover Sport L461 and Range Rover Velar L560. It is petrol-specific, so confirm your engine is the 3.0L Ingenium petrol before ordering.
What are the signs a crankcase breather cover is failing?
A failing crankcase breather cover typically causes oil leaks, a whistling intake, rough idle, or a crankcase pressure fault on the 3.0L Ingenium petrol. Cracks or a failed diaphragm are common. Replacing the cover restores proper crankcase ventilation.
