In this video, I will show you how to replace the PCV valve on an OM642 engine in a 2010 Mercedes S350 CDI. This is a very simple procedure but will save you from many troubles. The part is a very simple part that is composed of a rubber diaphragm and a spring inside. Over time the rubber vulcanizes and loses elasticity. Replacing it will reduce the black smog and oil-burning issues.
