Porsche 996 911 Air Oil Separator (AOS) Replacement DIY – PCV System (1999-2008 Carrera 3.4L & 3.6L)

Porsche 996 911 Air Oil Separator (AOS) Replacement DIY – PCV System (1999-2008 Carrera 3.4L & 3.6L)

►Porsche 996 911 engines feature an air oil separator, also commonly referred to as the AOS. If this is failing, you can experience numerous symptoms, and although they can show up at any time, most begin to show around 60,000-80,000 miles. Some symptoms of a failing PCV system on your Porsche 996 may be more difficult to diagnose than others, with the most common being:

Vacuum Leaks
Illuminated Check Engine Light
Illuminated Oil Pressure Light
Rough Idle
High Oil Consumption
Lean & Misfire Codes
Idle Regulation Codes
Whistling Noise from Engine Cover
Oil Leak From Rear Main Seal

The symptoms are easily diagnosed as other failures; however, the PCV system should always be checked early on in the diagnostic process as it’s easy to replace/repair, and the parts are affordable.

Today, Michael Hidalgo, one of FCP Euro’s resident 996 enthusiasts, is here to show you how you can gain access and replace your Porsche 996 AOS, step-by-step at home in your garage.
