1378492 Gasket | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta engine gasket from the Engine system group, used to form a sealed joint between mating engine components and prevent fluid or pressure loss. It is the current replacement for the earlier gasket 463829 and serves petrol marine engines in the AQ and 200-series families. Gaskets are single-use items and should always be renewed whenever the joint they seal is disturbed.

🔌 Function

The gasket sits between two machined engine faces to create a leak-tight seal that contains fluids and pressure while compensating for minor surface irregularities. It is designed to be replaced each time the joint is opened to restore full sealing integrity.

⚠️ Common Signs of Failure

• Visible fluid seepage, weeping or staining around the joint face
• Hardened, brittle or cracked gasket material found on disassembly
• Loss of pressure or compression at the sealed joint
• Crushed, distorted or blown-through sections of the gasket
• Repeated need to retighten fasteners at the joint to stop a leak

🛠️ 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
