I was hoping to get some help regarding an oil leak I was having at the rear of my cylinders on the passenger side of the car. I recently replaced the 3 expansion plugs that everyone says must be replaced and it stopped what I thought was my only oil leak. I started noticing a burning smell and figured out that whatever is at the rear of my cylinder block being held on by what seems to be 4 screws is leaking oil directly onto my exhaust. It has a vacuum line attached to it as well. Is this something I could possibly replace myself? I did the expansion plugs without any difficulty but I cannot find many posts about my particular problem so I did not want to venture into uncharted waters. Can I undo the screws holding this part on without messing anything up? I believe the part is called a Cam Breather but I could be mistaken. Any info would help me dearly and I thank anyone who could take any time to help a fellow Benz owner out.

 

It's called the "oil centrifuge" or "oil separator". It has two replaceable seals.

 

Thanks Rodney. I replaced the housing as a whole. It has a rubber seal around it that wasnt keeping the oil in the housing. I put the new one on and all seems good at the moment. Im crossing my fingers I have no more trouble with this car. Its the dreaded 2006 CLK350. Thanks again for your help.

 

Just been told by the dealer that oil was seeping from the "centrifuge cover." Is this the same thing? If so, how did you replace it???
