Function of the Oil Separator in the S63N Engine

The oil separator in the S63N engine plays a crucial role in the crankcase ventilation system. Its tasks include:

• separating oil particles from gases before they return to the intake,
• limiting oil ingress into the intake system under high boost pressure,
• stabilizing crankcase pressure during dynamic driving,
• assisting in maintaining the cleanliness of intake channels and boost components.

Thanks to this, the engine maintains more consistent operating parameters, and the lubrication system is less susceptible to uncontrolled oil loss.

Benefits of Using an Original BMW Separator

In high-performance units like the S63N, a precisely selected oil separator directly impacts engine durability and refinement. An original part from the Oil Filters group ensures:

• appropriate separation efficiency at high RPMs and high thermal loads,
• compatibility with the factory crankcase ventilation and intake system in BMW M5 F10 and M6 F12/F13,
• correct fitment to mounting points and hoses without the need for modifications.

Choosing a separator that matches the factory specification reduces the risk of unstable idling, excessive smoking, or oil contamination of the intake, which is particularly important in cars driven dynamically.

Part Condition and Service Application

The offered oil separator is a BMW part intended for service application in the S63N engine. It is suitable for both standard replacement of worn crankcase ventilation components and for larger maintenance tasks within the powertrain, e.g., after software or boost system modifications.

Replacing the separator is recommended when you observe increased oil consumption, oil traces in the intake, or issues with smooth engine operation when the oil is hot. Using an original part helps restore the factory parameters of the ventilation system.

Fitment by OEM Number and Selection Support

To ensure the separator will work correctly with your engine, it is advisable to verify compatibility by OEM number and interchangeable part numbers. The product description provides the relevant designations to facilitate matching with specific BMW M5 F10 or M6 F12/F13 configurations.

You will find a step-by-step procedure and a list of questions to ask before purchasing a used part.

Related Lubrication and Oil Cooling System Components

The oil separator works in conjunction with other components of the lubrication system and indirectly affects the operating conditions of the engine oil. It is worth noting that engine overheating and incorrect oil temperature can accelerate the wear of components such as separators, crankcase ventilation hoses, or seals.
