21497512 Gasket | Genuine Volvo Penta Part

🔧 Product Description

OEM sealing gasket used in oil-filter housing and related engine-oil system locations across a broad group of Volvo Penta marine and industrial engines. It replaces earlier Volvo references 20823322 and 20546571. The gasket seals mating faces against pressurised engine oil and should be renewed whenever the associated housing or oil-system joint is dismantled.

⚙️ Key Features

• Genuine Volvo Penta oil-system gasket
• Current replacement for 20823322 and 20546571
• Used in oil-filter housing, oil-pump or oil-system sealing positions according to engine design
• Resistant to hot engine oil and normal crankcase temperature
• Engine type: Four- and six-cylinder turbocharged marine diesel plus 16-litre industrial/generator diesel

🔌 Function

Seals the oil-filter housing or related oil-system joint to retain engine-oil pressure and prevent external leakage or air entry.

⚠️ Common Signs of Failure

• Oil seepage around the filter housing or oil-system joint
• Oil collecting on the engine block or in the bilge
• Falling engine-oil level
• Gasket hardened, split or compressed
• Leakage returning after housing removal and refitting

🛠️ 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
