Diagram Ref No 1

During normal operation, combustion gases and oil vapours accumulate within the engine crankcase. The Air Oil Separator separates oil particles from these gases, returning the oil to the engine while directing cleaned vapours back into the intake system for combustion. This process helps maintain engine efficiency, reduce emissions and prevent excessive oil contamination within the intake tract.

The Air Oil Separator is one of the most recognised maintenance items on Porsche M96 engines. As the internal diaphragm ages, the separator can lose its ability to regulate crankcase pressure correctly, resulting in a variety of performance and drivability issues.

Manufactured to OE Match standards, this replacement unit restores proper crankcase ventilation and helps maintain the performance and reliability expected from your Porsche Boxster.

What Does the Air Oil Separator Do?

The Air Oil Separator forms part of the Positive Crankcase Ventilation (PCV) system.

Its primary functions include:

• Separating oil from crankcase gases
• Returning oil back into the engine
• Regulating crankcase vacuum
• Reducing oil consumption
• Supporting emissions control systems
• Maintaining engine efficiency
• Preventing excessive oil contamination of the intake system

A correctly functioning AOS helps the engine breathe properly while minimising oil carryover into the intake manifold.

Oil separator. One of the most common failures in the Boxster or 996 is the Air/Oil Separator, also referred to as the AOS. 

This Air/Oil Separator product ref 996.107.023.55 also includes the rubber below 996.107.237.52 and jubilee clip 999.512.551.01



The AOS is basically a small diaphragm distillery which distills the minute amounts of oil mist in the crankcase, liquifies it and sends it back to the crankcase. The "clean" air is now sent into the air intake (after the throttle body) to be burned off by the engine.

When the AOS starts to fail it cannot separate all of the oil out of the mist and some liquid oil is sent to the air intake.

A few drops of oil is enough to generate the GREAT SMOKE BOMB for which our cars are famous for.

A big smoke bomb once in a while is completely normal, due to the architecture of the flat-6 engine, which may let a drop of oil flow into one of the combustion chambers sporadically.
