I have owned 3 Ford F-250 diesels, the last of which was the 2005, 6.0 diesel, loved the truck until we were on our way to a shoot in Utah. Got off the ramp and the entire truck was engulfed in blue/gray smoke, limped into campground with our fifth wheel, and was stranded for 9 days, the ford dealer was really great with us, as the truck was just out of 5 years warranty, but only had 86,000 miles on it and they went to ford diesel desk in MI with a request for help with repairs and they granted help to the tune of $3,000.00. Here's where the story gets interesting, the head diesel mechanic says to me, "are you aware of all the problems with the 6.0", my answer NO, he says be sure to look up on internet " problems with ford 6.0 Diesel engine, so I did, and man what a shocker, ford spent over 1 billion dollars on warranty issues. Sued Navistar and was awarded 500 million! Now we got our truck back, and our part of the bill was $5,500.00,on Saturday, and departed Sunday for home, we got to just north of town, and lost all turbo boost, limped all the way home, and took truck to our local ford dealer and they said the engine failure had an impact on the turbo and its failure! Another $1500.00, then 4 months later it started stalling, as you started to stop at traffic lights, so they put a flight recorder on it and found that an internal sensor called a chip detector was bad, and replacement would be $2500.00.
That's when I decided to go with a gasser! The original problem that caused all this was an inter turbine cooling tube, once it fails it ingests cooling fluid and the turbo forces the coolant into the entire engine! The diesel tech told me he put all the internal engine parts through the parts washer 6 times to get all the residue off the parts! Now thats why i have a reluctance to buy another diesel. That repair bill took all of my shooting entry fees and travel money for 6 months.
