Purpose and technical function

The described breather hose is a component of the crankcase ventilation system in the Mercedes Sprinter W906 with the OM651 diesel engine. Its task is to provide controlled discharge of blow-by gases from the rear of the power unit, in order to limit overpressure in the crankcase and reduce stress on seals.

A properly selected ventilation hose:

• stabilizes the operating conditions of the lubrication system,
• reduces the risk of oil leaks at connections and seals,
• supports the maintenance of the correct operating characteristics of the diesel engine.

Construction and system fitment

The breather hose has been designed for specific routing in the rear part of the power unit, taking into account the layout in the Sprinter W906 engine bay. The shape and diameter of the hose are adapted to factory connectors, which facilitates installation and ensures a tight connection with other system components.

Thanks to a design consistent with solutions used by Mercedes, the hose works with the factory engine gas recirculation system without the need to modify other components.

Operational characteristics

The element comes from a diesel-powered vehicle, therefore its flow parameters and resistance to operating conditions are adapted to the specifics of a diesel engine. The used condition of the part allows for an economical repair while maintaining the original characteristics of the ventilation system.

Replacing a worn or leaking breather hose with a functional element of this type helps to:

• reduce unwanted oil vapors in the engine bay,
• maintain stable pressure in the crankcase,
• limit the risk of secondary failures related to excessive blow-by.

Benefits of using an original used component

Using an original hose from the Lines, hoses and pipes category allows for maintaining factory installation routing and proper fitment with other OM651 engine components. This is a particularly beneficial solution for servicing commercial vehicles, where the predictability of system behavior and repeatability of operating parameters are essential.
