Key Features

- Official Volvo Penta part name: gasket
- Commonly identified as a valve cover / rocker cover gasket
- Used on select classic MD-series Volvo Penta diesel engines

Engine Compatibility
The clearest matching application trail connects 859120 to Volvo Penta MD1, MD2, MD3, MD11, and MD17 engine families, with several references also listing variants such as MD1B, MD2B, MD3B, MD11C, MD11D, MD17C, and MD17D. Fitment should still be confirmed against the exact engine model and serial number before ordering.
Serial Number Fitment Notice
Please confirm fitment by engine model and serial number before ordering. This is especially important on older Volvo Penta engines, where part usage can vary by engine version and service history.
When This Part Needs Replacement
Replace this gasket whenever the valve cover is removed and the original gasket is leaking, torn, brittle, compressed, or no longer sealing correctly. It is also a smart replacement item during valve-train service, top-cover removal, or engine refresh work. The service guidance here follows the part’s valve-cover gasket function.
Installation Notes
Install only on the correct Volvo Penta application and verify the removed gasket against the part number, engine model, serial number, and gasket shape before ordering. Matching the original part exactly is the safest approach on older MD-series engines.
Alternate / Superseded Part Numbers
