Exhaust Manifold Bolt for the Rover V8 petrol engine, threaded 3/8" UNC and 1 1/8" long.

The bolt secures the exhaust manifold to the cylinder head, clamping the manifold flange against its gasket to form a gas-tight seal. Renew when refitting a manifold, as heat-cycled fixings can seize or lose clamping load.

Frequently asked questions

What is the ERR6734 manifold bolt and what does it do?
The ERR6734 is an exhaust manifold bolt for the Rover V8 petrol engine, threaded 3/8" UNC and 1 1/8" long. It clamps the exhaust manifold flange against the cylinder head so the joint stays gas-tight under heat and pressure.
Which Land Rovers use the ERR6734 manifold bolt?
The ERR6734 fits the Discovery 1 (1989-1998) V8 EFI petrol from VIN FA393361 to WA799999, and the Discovery 2 (1998-2004) V8 petrol, where it's the flanged-head screw for the exhaust manifold. Check the Discovery 1 chassis number falls within that VIN range.
Should exhaust manifold bolts be replaced when refitting?
Yes, the ERR6734 manifold bolts are typically renewed when a V8 exhaust manifold is refitted. Heat-cycled fixings can seize or lose clamping load over time, and shearing on removal is common. Fresh bolts help the manifold flange seal cleanly against the cylinder head.
