🔌 Function

The gasket forms a compressible seal between two bolted components in the inlet and exhaust system, preventing leakage of air, exhaust gas or oil at the joint. It also compensates for minor surface irregularities between the mating faces.

⚠️ Common Signs of Failure

• Visible leakage or staining around the joint face
• Hissing or whistling from an air or exhaust leak under load
• Hardened, cracked, flattened or brittle gasket material on inspection
• Loss of boost pressure or uneven running traced to a leaking joint
• Soot tracking or carbon streaks around the sealing surface

🛠️ Service Notes

• Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
• Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
• Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
• Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
• Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
