I smelled hint of raw fuel when the engine was warm for 1-2 months prior to the obvious problem. 3-4 weeks prior to professional inspection there was white smoke out of the exhaust for 1-2 minutes. This smoke was associated with rough idling that when away completely until the next cold start up. The precipitating event for professional inspection was raw fuel spraying onto the trailer that was being pulled. Inspection revealed raw fuel pooled on the horizontal engine surfaces and raw fuel in the cooling system. This was verified by manufacturer's dealer service department and found to be a leaking fuel injector cup. It will require changing all the fuel injector cups. The dealer service agent reported that this same problem has been several times in these particular models. It is usually a warranty item. This has not been repaired yet as this vehicle's warranty has expired by time limit but not mileage. The manufacturer has denied any obligation to help restore the vehicle to safe operation given that it seems to run unimpaired from a performance standpoint.

Our company has purchased a 2003 ford f350 in july 2003 it has 18,000 miles on it and has had 3 turbo's installed is runs rough lacks power and continues to have problems we do not drive the truck often but is run daily. I can't imagine the problems we would have if driven 500 miles a week . My concerns are what will happen when the warranty runs out and I need to pay 1500 for a turbo or new engine or injectors.
