Elring 659.810 Engine Valve Stem Oil Seal - Intake

Elring Valve Stem Oil Seal for Subaru Engines

Elring 659.810 is an engine valve stem oil seal made from FPM (fluoride rubber) for precise sealing in Subaru applications. With an 11.0 mm inside diameter, 13.0 mm outside diameter, and 8.0 mm thickness, it is built for 6 mm valve stem diameter applications where controlled oil sealing is critical.

Key Features

• FPM (fluoride rubber) construction for heat- and oil-resistant sealing performance
• 11.0 mm inside diameter, 13.0 mm outside diameter, 8.0 mm thickness
• Designed for 6 mm valve stem diameter applications
• Engine valve stem oil seal for gasket and sealing system service
• Elring part number 659.810 for direct identification

Detailed Description

This Elring valve stem oil seal is used in Subaru engine sealing service where valve guide oil control is required. The FPM material helps maintain sealing integrity in high-temperature engine environments, while the listed dimensions support accurate fitment for the specified Subaru WRX, WRX STI, Forester, Impreza, Legacy, Outback, Baja, and Saab 9-2X applications. If you are servicing a Subaru WRX or Subaru Impreza engine and need a valve stem seal with the correct 6 mm stem diameter specification, Elring 659.810 is a direct-reference part to verify against the original seal dimensions. This part cross-references 13207AA030 and 13207AA050 for the same application.

What It Helps Address

• Oil entering the combustion chamber through worn valve stem seals
• Blue exhaust smoke caused by valve guide oil leakage
• Excessive oil consumption from deteriorated stem sealing
• Valve train sealing issues during cylinder head service
• Restoration of proper oil control in Subaru engine repairs

Installation Notes and Tips

• Verify valve stem diameter, inside diameter, outside diameter, and thickness before installation.
• Confirm whether your application uses intake position seals where noted in the fitment data.
• Inspect valve guides and related sealing surfaces for wear before installing new seals.
• Use clean engine assembly practices to avoid damaging the FPM sealing lip during installation.
• Match the seal to the exact engine specification for Subaru WRX, Subaru WRX STI, and Subaru Impreza service work.

Quality Assurance

Elring is a recognized name in engine sealing systems, and this valve stem oil seal is specified with exact dimensional data to support accurate parts selection for Subaru engine repair. Part number 659.810 should be matched to the original application and measurements before installation.
