Volvo Penta 861700 is a genuine OEM valve seal used in select Volvo Penta marine diesel engine applications.

Key Features
- Genuine Volvo Penta part number 861700
- Identified in public listings as a valve seal
- Commonly described as a valve stem seal in marine parts listings
- Small engine sealing component used in valve train service
- Best matched by exact part number, engine model, and serial number
Engine Compatibility
Public fitment references link Volvo Penta 861700 to a range of Volvo Penta diesel applications, with especially clear public references for D6 engines, and broader aftermarket references also tying it to some D4, D6, and KAD-series applications. Because public fitment references are not fully consistent across all sellers, this should be treated as a serial-number-confirmed engine part rather than a universal fit.
Serial Number Fitment Notice
Please confirm fitment by engine model and serial number before ordering. Volvo Penta’s parts support emphasizes identifying the exact engine when sourcing replacement parts, which matters here because public listings agree on the part identity more than they agree on the full engine coverage.
When This Part Needs Replacement
Replace this valve seal during cylinder head or valve train service when the existing seal is worn, hardened, leaking, damaged, or no longer controlling oil properly. It is also commonly replaced during top-end service or engine rebuild work. This replacement guidance is based on the part’s function as a valve seal.
Installation Notes
Install only on the correct Volvo Penta engine application. Matching by part number, engine model, serial number, and removed-part verification is the safest approach. Because this is an internal engine sealing component, installation is best handled during proper engine disassembly and service.

Parts Desk Insight
The strongest public data here is on part identity: 861700 is clearly a Volvo Penta valve seal. The fitment trail is real, but it spreads across multiple diesel families in public listings, so the safest Marisol Marine sale is against the exact engine serial number rather than broad engine-family assumptions.
