What is the role of the crankcase ventilation valve in an Audi 80?

I am looking to understand the function of the crankcase ventilation valve and how it operates in an Audi 80 engine. Can someone provide a clear explanation of its purpose and how it contributes to the performance of the vehicle?

The crankcase ventilation valve is responsible for regulating the flow of gases from the engine's crankcase back to the intake manifold. This helps prevent pressure build up and allows for efficient burning of fuel. My advice would be to regularly check and clean the valve to ensure optimal performance.
