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 this manifold bolt and what does it do?
This exhaust manifold bolt secures the manifold to the cylinder head on the Rover V8 petrol engine, clamping the manifold flange against its gasket to form a gas-tight seal. It is threaded 3/8" UNC and is 1 1/8" long.
Which vehicles does ERR6734LR fit?
ERR6734LR fits the Discovery 1 and Discovery 2 with the V8 petrol engine, for the exhaust manifold. Discovery 1 applications run from VIN FA393361 to WA799999. Confirm your engine and VIN before ordering.
How many manifold bolts are needed?
Several bolts typically secure each exhaust manifold on the Rover V8. It is best to renew the full set when refitting a manifold rather than reusing some old bolts, so order the quantity your engine needs for the job.
Should manifold bolts be replaced when refitting?
Yes, renew these manifold bolts when refitting a manifold. Heat-cycled exhaust fixings can seize or lose clamping load over time, so fitting fresh bolts helps keep the manifold flange sealed against its gasket on the V8.
