Hello there, I've been asked to look at a 220 Daewoo excavator that's adding over a gallon of fuel to the oil in 8 hours. Well pulled the fuel pump off and checked it and no leaks so I pulled the injection pump and no obvious leaks so I filled the fuel chamber and added a little pressure and worked the pump nothing leaking into the oil chamber. Mechanic before me told them the fuel is going around the rings well ok. It runs perfect no smoking to show over fuel or wet stacking.
I'd like to get the injection pump tested but I'm in remote Alaska so that's not an option. Ya this one has me scratching my head so any ideas
