0000535658 Valve Stem Seal For Benz M271 Older Model 1.6L 1.8L And 2.0L Four-Cylinder Gasoline Engine Engine Seals

1. Core Product Identity

• Product Name: Valve Stem Seal

• Part Number: 0000535658 (This is typically an aftermarket or supplier-specific number used for inventory and management).

2. Primary Function

Its core purpose is to seal the engine's valve stems. Specifically:

• Prevents Engine Oil from Entering the Combustion Chamber: As the valves move up and down, engine oil lubricates the valve stems. The valve stem seal ensures this oil remains in the cylinder head for lubrication and does not leak down the valve stems into the combustion chamber below.

• Ensures Proper Engine Operation: If the valve stem seals become worn, aged, or damaged, engine oil can seep into the combustion chamber and be burned. This results in oil burning (characterized by blue smoke from the exhaust and rapid oil consumption). Furthermore, excess oil in the combustion chamber can create carbon deposits, which harm engine performance and emissions.

3. Vehicle Compatibility

• Brand: Mercedes-Benz

• Compatible Engine Model: Older models of the M271 series engine.

  • The M271 is a classic Mercedes-Benz 1.6L, 1.8L, and 2.0L four-cylinder gasoline engine, widely used in many Mercedes models from the early 2000s to the early 2010s.

  • Typical Vehicle Applications Include:

    • Mercedes C-Class (W203)

    • Mercedes E-Class (W211)

    • Mercedes SLK-Class (R171)

    • Mercedes CLK-Class (C209/A209)

    • And various other models.

4. Product Positioning & Usage Scenario

• Meaning of "Older Model": This clearly indicates that this part is designed for earlier production versions of the M271 engine. Throughout an engine's production life, parts may undergo minor revisions or changes. This seal is specifically designed to match the specifications of these older engine versions.

• Primary Usage Scenario: Engine repair and maintenance. This part is typically replaced during an engine overhaul (e.g., during decarbonization or valve replacement), especially when symptoms like oil burning or oil leakage from the valve cover area appear. Replacing all valve stem seals is a common repair procedure.
