Valve covers have a tendency to eventually leak oil making a mess of the engine. While it is not difficult to change the valve cover gasket on the Mercedes-Benz M104 engine you will need to remove a few things first. One thing that a beginning DIY'er thinks will help but only causes problems is putting RTV sealant on the head or gasket. A properly clean, seated and tightened valve cover and seal does not need any RTV. Most people lather on the RTV which just ends up getting into the valve train and causing all kinds of problems. If you do the job correctly and there are no problems with the head or valve cover you do NOT need to use RTV.
It is a very good idea to perform this work when the engine is cold.
