Kent found a solution for one problem but another has cropped up. See how he plans to deal with replacing an old rock hard plastic breather tube seal and elbow on the Mercedes 601 602 and 603 diesel engines. This is a very common oil leak problem on the 1986 to 1993 190D 300SDL 300D 300TD 350SD 350SDL and 300D 2.5.
