Do oil separators go bad?
A bad or failing vent oil separator will also fail to remove condensation from oil. Believe it or not, if you stay on top of routine service and maintenance, there shouldn’t be a problem with the vent oil separator. However, it’s quite possible for this condition to occur even with proper service.
Why does my 996 Boxster blow smoke out of the exhaust?
996, 997’s, and Boxsters use an oil air separator which basically reduces oil vapor that recirculates in the engine. Unfortunately, they use a rubber diaphragm that is prone to failure. The result is excessive smoke out of the exhaust on start up and driving.

Why does my Porsche Boxster have an AOS problem?
The AOS has caused numerous issues on Porsche engines and is an item to be closely monitored. As the membrane in the AOS fails, oil is sucked into the air intake.
