I have a Ford 2004 F250 Super Duty Crewcab with the 6.0 l turbo diesel engine. One month ago I was on my way from central CA, towing a 28ft. 5th wheel, to Oregon to pick up a 34ft. 5th wheel. About 250 miles into the trip I got a check engine lite. The truck had only 7500 miles on it. I pulled into a Ford dealer in Sacramento and they informed me that the turbo charger needed to be replaced. One day later the truck was complete and we we off again. After I picked up the 5th wheel we headed for the Oregon coast. Returning down the coast to CA we noticed a smell of diesel fuel in the truck cab. The smell didn't last long. When I returned home I called to get the scheduled oil change at the Ford dealer. They then informed me that I had excess fluid in the crankcase and they suspected that the excess was diesel fuel. They also informed me that there was a recall for replacement of the injector harness. Changed the oil and they told me to return the truck after 100 miles to check for diesel fuel in the crankcase. I have not returned yet. Does anyone have any idea what could have caused the diesel fuel to get into the crankcase? The Ford dealer won't tell me anything. I now understand that there are two more recalls.
