• preservation of the original mounting geometry and connection points.

Benefits of Using an Original Valve Cover

Using the factory valve cover on an AMG M156 engine allows for maintaining the unit's operating parameters at the level intended by the manufacturer. The original geometry and material minimize the risk of leaks, oil spills, and improper operation of the crankcase ventilation system.

Key benefits include:

• secure fit to the cylinder head without modifications,
• maintenance of correct lubrication and crankcase ventilation system operation,
• preservation of the original engine bay appearance in W164, W204, and W212 AMG models.

Installation and Operational Characteristics

The left valve cover for the AMG M156 is structurally designed for installation in its factory location, using the designated mounting points. Its placement on the left side of the vehicle facilitates part identification during servicing and selection of the appropriate gasket and accompanying accessories.

When replacing, it is recommended to:

• inspect the mating surface on the cylinder head,
• use a new gasket compatible with the AMG M156 engine,
• thoroughly clean the contact area of oil and deposits before installation.

This approach helps reduce the risk of recurring leaks and ensures stable power unit operation in the long term.
