Hello Steve
The Injection pump is pushing fuel into the crankcase because (probably)there is a bad O-ring in the head of the pump. you need to get this fixed, cause diesel in the oil will wash the liner walls, causing scoring. After you the the pump head fixed, I'd check the fuel bypass (between the supply pump and the injector pump) a piece of dirt in there will cause exces fuel pressure in the pump head, thus blowing out the O-rings. Good luck, Don
