Eliminate the common boost leaks caused by the factory PCV valve on your 2.0T FSI engine using this PCV plate. Once they begin to fail, your boost begins to leak into the crankcase and cause positive pressure, which is also associated with oil mist appearing in several spots of the engine bay. These take place of the breather plate on the front of the valve cover and eliminate the PCV valve and hoses that are associated with it. This will retain the block breather hose, which will easily clip onto the preinstalled barb on the plate.
