Audi B8 A4 2.0T Emissions Service Kit
The breather, or also commonly called the PCV or oil separator, allows the crankcase to expel air without losing any oil. This system is designed to give gases a way to escape in a controlled manner from the crankcase.
It is critical that the parts of the PCV system be kept clean and open; otherwise airflow will be insufficient. A plugged or malfunctioning PCV system will eventually damage an engine.
