🔌 Function

Seals the joint between the cylinder head exhaust ports and the manifold so hot gas cannot escape into the engine space.

⚠️ Common Signs of Failure

• Ticking or puffing from the manifold joint that eases as the engine warms
• Sooty black witness marks around the manifold flange
• Smell of exhaust in the engine space
• Gasket burnt through or blown out between two ports
• Manifold flange face distorted or the studs pulled

🛠️ Service Notes

• An exhaust leak in an enclosed engine space is a carbon monoxide risk, so treat a blowing manifold joint as urgent
• Renew the manifold nuts and check the studs for stretch while the manifold is off
• Check the flange for distortion with a straight edge before fitting the new gasket
