Purpose and compatibility with the M112 engine

The presented oil sump has been designed to work with the M112 petrol engine used in Mercedes W163, W210, W220, and W211 class models. This means it fits the factory block geometry, has the correct mounting point placement, and is compatible with the original lubrication system. As a result, the component maintains the oil flow parameters specified by the manufacturer, which is particularly important when operating in varied road conditions.

Construction and function in the lubrication system

The oil sump plays a key role as a working reservoir for engine oil, responsible for:

• maintaining the appropriate oil volume for the M112 unit,
• stabilizing the oil during acceleration, braking, and cornering,
• working with the oil pump suction system,
• dissipating heat from the oil through contact with the environment.

Thanks to its factory design, the sump ensures proper shaping of the bottom and channels, which reduces the risk of the oil pump sucking in air and supports even lubrication of all key engine components.

Application in Mercedes petrol vehicles

The component has been developed for units powered by petrol fuel, which means it is adapted to the thermal characteristics and loads typical of M112 engines. In practice, this translates into:

• appropriate structural rigidity under high oil temperature conditions,
• compatibility with factory seals and mounting hardware,
• maintaining the manufacturer-specified ground clearance relative to the chassis.

Such fitment is particularly important for vehicles used intensively, where the stability of lubrication parameters has a direct impact on engine durability.

Characteristics of the used part

As a used part, the oil sump has already been in service in a vehicle, yet it retains its structural and functional properties. This solution allows for an economical repair of the lubrication system while maintaining the original manufacturer's specifications. By choosing such a component, you gain:

• factory fitment to the engine block and accessories,
• compatibility with original mounting points,
• the ability to quickly replace a damaged or leaking sump without structural modifications.

Support for lubrication system upgrades
