21487571 Gasket | Genuine Volvo Penta Part

🔧 Product Description

A moulded cylinder-head cover gasket used to seal the valve cover on Volvo Penta D11 heavy-duty diesel engines.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1180-83VE

• Engine Family: TAD

⚙️ Key Features

• Oil-resistant moulded sealing material
• Correct D11 valve-cover profile
• Seals around the rocker and valve-train compartment
• Designed for repeated heat cycling
• Direct service replacement

🔌 Function

The gasket prevents lubricating oil and crankcase vapour from escaping between the cylinder head and valve cover.

⚠️ Common Signs of Failure

• Oil seepage around the cover
• Oil smell or smoke on hot components
• Gasket hardened or flattened
• Oil mist in the engine compartment
• Leakage returning after cover removal

🛠️ 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
