If built like most, the valve cover will have a fitting with a fairly large hose leading away from it.
The PCV valve (Positive Crankcase Ventilation) is found in this line.

This allows fumes forming within the engine oilways sometimes pushed out by minor blowby of the cylinders to be routed back to the air intake so they combust in the engine instead of being vented into the air, something we didn't worry about 50 years ago.

What is a PVC valve


It is a device for regulating the passage of air through the crankcase and into the intake manifold, thereby ventilating the crankcase of combustion fumes that would otherwise contaminate the oil faster than normal. PVC stands for Positive Crankcase Ventilation if not in that order, Audi probably means in the german sense of Positive Ventilation, Crankcase valve. It's often a 3-4" diameter puck-like device with one pipe underneath it.

    I think it is in the valve cover. see illustrations from shop manual.



    Positive Crankcase Ventilation System Overview The Positive Crankcase Ventilation (PCV) System (Figure 132)cycles crankcase gases back through the engine where they are burned. The PCV valve regulates the amount of ventilating air and blow-by gas to the intake manifold and prevents backfire from traveling into the crankcase. The PCV valve should be mounted in a vertical position. On some applications, the PCV system is connected to the evaporative emission system (refer to the VECI decal). located on the underside of the hood or on the radiator cooling fan shroud.
