I have a big 600 diesel as well that had been sitting awhile. The fuel must have leaked through the older Bosch pump and into the crankcase. I didn't realize it as we were trying to start it, but it did start and run pretty good until I noticed fuel trying to spit out the oil dipstick. I shut it off (it had ran about 3 or 4 minutes) and figured there is obviously a seal out in the pump.
Would anyone know if that seal would happen to be an easy fix, or does the pump have to come off. Thanks again for any help - Bob
