903 Cummins in a 4840 Massey...gave a little shudder and then some black smoke while under load, now has a slight
miss, also fuel dilution in crankcase. Could a bad injector cause fuel in oil, or as I have been told, is it the seals in
the injection pump? Maybe both?? Have been using BG diesel fuel conditioner religiously in this low-sulfur fuel....
