How to replace AUDI (VW) PCV valve

PCV is an acronym for positive crankcase ventilation.
The PCV Valve is a very common replacement item on many engines today. It's called the PCV valve for short but it stands for Positive Crankcase Ventilation. When your engine spins it many times collects pressure in the crankcase area, and it has to escape to relieve pressure on the motors bearings and seals. The PCV valve and PCV system is typically located near the intake manifold, and many times comes right off of the valve cover. It is very simple to replace the PCV valve, and you can do so by simply unscrewing it, and screwing in the new valve. We recommend using a little bit of teflon tape or paste to make sure you do not get any oil leaks.
Example (see picture below): 2,4 ltr. Audi V6 engine (BDV, AMM)

    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.
