Car Fix DIY Videos

►Audi S4 B8 and B8.5 3.0t engines feature a crankcase ventilation system, commonly referred to as the PCV, crankcase breather, or air/oil separator. 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 Audi B8 are 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

Although Audi doesn’t consider the PCV system a regular maintenance system, it’s well known that these parts fail regularly. 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 Cory Calvin is here to show you how you can gain access to your Audi’s PCV system and how to replace it, step by step.
