Hey folks, I have an 89 190D 2.5 Diesel injection pump leak. It appears to be coming from under the barrels that screw into the top of the pump and where the injector lines screw on. On my old 220D I had the same problem and was an easy fix...old age, shrunken o-rings=replacement time. 1) Are there O rings under the barrels? 2) can they be removed with the pump on the engine? 3) Has anyone ever done it on this engine? Anything to look out for? Thanks mucho! Clip....BTW any idea on where to get the special socket to remove the barrels? Look like about 30 fine splines or so.........
