Crankcase Breather Cover for the 3.0L Ingenium AJ20P6 six-cylinder petrol engine, part of the positive crankcase ventilation system.

The moulded cover closes the crankcase ventilation chamber on the camshaft cover, sealing the oil separator circuit that draws blow-by gases out of the crankcase, strips entrained oil from them and returns the vapour to the induction side while the separated oil drains back to the sump. It seats on a gasketed face and is retained by a set of small fasteners.

A cracked cover or a hardened, distorted sealing face lets unmetered air into the crankcase ventilation circuit. Typical symptoms are an unstable idle, oil misting or wet residue around the camshaft cover, audible whistling under load and crankcase pressure fault codes. The sealing gasket should always be renewed whenever the cover is disturbed.

Frequently asked questions

What does the crankcase breather cover do?
The crankcase breather cover closes the crankcase ventilation chamber on the camshaft cover of the 3.0L Ingenium AJ20P6 petrol engine. It seals the oil separator circuit that draws blow-by gases from the crankcase, strips out entrained oil and returns the vapour to the induction side while separated oil drains back to the sump.
Which engine and models take this breather cover?
This breather cover fits the 3.0L Ingenium AJ20P6 petrol engine only, across the Discovery 5, New Defender L663, Range Rover L460, Range Rover Sport L461 and Range Rover Velar. It supersedes part LR181446. It won't fit diesel or other petrol engines.
What are the symptoms of a failed breather cover?
A cracked cover or hardened, distorted sealing face lets unmetered air into the crankcase ventilation circuit. Typical symptoms are an unstable idle, oil misting around the camshaft cover, whistling under load and crankcase pressure fault codes. Renew the sealing gasket whenever the cover is disturbed.
Do I need a new gasket when fitting the cover?
Yes, renew the sealing gasket whenever the cover is disturbed. The cover seats on a gasketed face and is retained by small fasteners. Reusing a hardened gasket risks an air leak into the ventilation circuit and the idle and fault-code symptoms that come with it.
