ERR7394 Genuine Right Exhaust Manifold V8 Discovery Defender

ERR7394 is the Genuine Land Rover right hand exhaust manifold for the Rover V8, covering the Range Rover Classic, Discovery I, Discovery II and Defender. It arrives in the Land Rover factory carton with the Genuine Parts label and the part number printed on it.

This is the passenger side manifold. The left hand side is ERR7393, and the two are not interchangeable, so check which one you are replacing before you order. Most people find out the hard way that a V8 needs the right casting for the right bank.

Manifolds on these engines crack, and they usually crack at the same places. You hear it before you see it, a ticking that is loudest on a cold start and fades once everything has expanded. A warped or split manifold also leaks exhaust gas under the hood, which is the part worth taking seriously rather than living with.

Land Rover ran this number through several revisions. ERR7394 is the current one and the factory lists it as the replacement for ERR7394K, ERR5023 and ERR3454. If your manual or your old invoice points at any of those, this is what the factory supplies in their place.
