2003 E350 7.3 Massive Oil Consumption Issues

[alsatropine]

OK guys. Ive had the pleasure of working on a few ambulances in our fleet, trying to save money on labor, ect. Plus its a great learning experience for me. I started out with the ambulance consuming massive amounts of oil. The first recommendation was that the seals had blown in the turbo. When I pulled the turbo, I did notice oil in the turbo where it shouldn't be. I replaced the turbo and allowed the ambulance to idle for a few hours before heading down the road. It ran like a scalded dog, didn't smoke much. I then parked it and checked the oil. It had already dropped almost a gallon. So the next recommendation was to pull the injectors. It took me a day, but I was able to pull all the injectors. I carefully laid them out and numbered every piece removed and which cylinder they were pulled from. Out of eight injectors, 4 of the orings ( the pink one ) is almost burned in half. Also on the tip of one of the injectors you can see where the brass washer was not seated properly and the combustion had made a little burn mark on the side of the injector. Here is my question. With the 4 orings nearly burned in half and the brass washer not seated properly on the end, could this be the culprit of that much oil being lost? Keep in mind that is having longer than usual crank times, and was smoking severely before I replaced the turbo. Now it just smokes a little less. I am replacing all the orings tomorrow, but is there anything else I need to look for before reinstalling the injectors? I did look inside and inspected the injector sleeves and none of them were cracked. Thanks for your time in reading the situation and any input will be greatly appreciated.


Sorry , forgot to mention there is oil in the diesel. Checked the tank and the pulled the fuel filter.
