Volvo Penta Gasket 859043

Volvo Penta 859043 is a genuine OEM gasket used as a valve cover / rocker cover gasket on selected Volvo Penta diesel engines. Volvo Penta’s official parts shop identifies part number 859043 simply as Gasket, while current replacement-market references consistently describe it as the valve cover gasket for Volvo Penta 2002-series engines.

This gasket seals between the cylinder head and the valve cover, helping contain oil and maintain a clean, reliable top-end seal. Current cross-reference listings also show 840440 as a replaced or associated earlier number tied to the same valve-cover application.

Serial Number Fitment Notice
Fitment should always be confirmed by engine serial number before ordering. Volvo Penta’s official parts guidance is to identify the exact engine, shield, or drive when selecting replacement parts.

When This Part Needs Replacement
Replace this gasket when:

• the valve cover is being removed for service
• the original gasket is brittle, flattened, or damaged
• oil seepage is visible around the valve cover
• the engine is being reassembled and a fresh gasket is needed for a reliable seal

Installation Notes

• Confirm fitment by serial number first.
• Match the gasket to the exact valve-cover sealing surface before installation.
• Clean both mating faces fully before reassembly.
• Replace the old gasket during service instead of reusing a compressed seal.

Parts Desk Insight
Valve cover gaskets are inexpensive compared with the mess and repeat labor that come from chasing oil leaks later. On older Volvo Penta 2002-series diesels, replacing the rocker-cover gasket any time the cover is removed is usually the cleaner move for a dry, dependable finish.
