Frequently asked questions

What does the exhaust manifold gasket do?
The exhaust manifold gasket seals the joint between the exhaust manifold and the cylinder head. It maintains a gas-tight seal at the manifold flange, preventing exhaust gas leaking between the head and manifold on the AJ V8 petrol engine. Supplied as a single gasket.
Which models and engines use this gasket?
This exhaust manifold gasket fits the Discovery 3 (2005-2009), Range Rover L322 (2002-2009), and Range Rover Sport L320 (2005-2009). It covers the AJ 4.4 V8 EFI (220kW) and 4.2 V8 Supercharged petrol engines. Confirm your engine variant before ordering.
What are the signs of a failed exhaust manifold gasket?
A failed exhaust manifold gasket typically shows as a ticking or blowing noise, loudest on a cold start, plus a smell of exhaust fumes. Heat cycling degrades the gasket until the manifold flange leaks. Left unsealed, it can affect running and let fumes into the engine bay.
How many exhaust manifold gaskets are needed?
The AJ V8 has two exhaust manifolds, one per cylinder bank, so a complete job typically needs two gaskets. This item is supplied as a single gasket, so order a pair if you're resealing both manifolds on your Range Rover or Discovery 3.
