Serial Number Fitment Notice
Fitment should always be confirmed by engine serial number before ordering. Volvo Penta’s official guidance is to identify the exact engine when selecting replacement parts, and that matters here because this gasket appears across multiple diesel engine families and cover arrangements.

When This Part Needs Replacement
Replace this gasket when:

• the timing cover is being removed for service
• the original gasket is brittle, compressed, or damaged
• oil seepage is present around the timing-cover joint
• the front cover assembly has been opened and needs a fresh gasket for reassembly

Installation Notes

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

Replaces / Cross Reference Numbers

• 859038
• Current listings present it as a timing cover gasket reference
• Related timing-gasket-set references also group it alongside 859039 and 829487 in some aftermarket kit listings.

Parts Desk Insight
Timing cover gaskets are inexpensive compared with the labor involved in reopening the front of the engine. On older Volvo Penta diesels, replacing the gasket during front-cover service is usually the cleaner move for a more reliable seal, especially when oil seepage is already showing around the cover area.
