Purpose and function of the turbo oil line

The turbo oil line in the OM651 engine is responsible for supplying engine oil to the turbocharger, ensuring its lubrication and dissipating heat from the bearings. Proper oil flow is crucial for rotor durability, stable operation of the turbocharger system, and reducing the risk of turbocharger seizure.

The original oil line used in OM651 units in Mercedes R172, W204, W212 and W639 models allows you to maintain the factory operating parameters of the supercharging system without the need for structural modifications.

Benefits of using the original oil line

The use of a component from the turbocharger group and parts from the original Mercedes production line brings a number of practical advantages:

• Factory geometric fit – proper hose routing relative to the turbocharger and engine block, without stress or unnatural bends.
• Appropriate diameter and cross-section – ensuring stable oil flow in accordance with the design assumptions of the OM651 engine.
• Mounting compatibility – the cable works with the factory mounting points in the engine compartment, making installation and service easier.
• Consistency with the turbocharger system – maintaining the turbocharger operating parameters as designed by the manufacturer.

Used condition and service aspects

The cable is offered in used condition, representing a reasonable compromise between repair costs and maintaining original build quality. This type of solution is particularly attractive when servicing older Mercedes R172, W204, W212, and W639 models, where both functionality and operating economy are important.

When replacing the turbo oil line, it is recommended to:

• checking the cleanliness of the oil channels in the engine,
• verification of the turbocharger condition for clearances and leaks,
• use of new seals at connection points,
• following tightening procedures in accordance with Mercedes service documentation.

Applicable to Mercedes models with OM651 engine

The Mercedes R172 W204 W212 W639 OM651 Turbo Oil Hose A6511801020 is designed for OM651 diesel engines used in various Mercedes bodies. Therefore, it can be used in repairs to both passenger cars and vans using this type of engine and its corresponding turbocharging system.
