Mercedes Diesel OM601 OM602 OM603 Common Oil & Fuel Leaks (which you may not see) 

I made this video, cus' nobody is showing the spot's on engine, all they are doing is just talking :D
This applies to the 1984 to 1989 190D, the 1986 to 1993 300D and 300TD, the 1986 to 1987 300SDL, the 1990 to 1991 350SD and 350SDL, and the early W140 diesel sedans.
Of course, there are other places oil can leak out of a diesel engine, but over the years these have proven to be the most common leaks (hidden ones)
Hope i somehow help all drivers of old mercedes cars (I am one of them :D) :)
