The 6.4L Power Stroke definitely has a better reputation for longevity than the 6.0L, but we know they have their fair share of gremlins to deal with as well...
How many of you have dealt with the following problems with Ford's '08-'10 Super Duty?
*Water in the fuel system (the worst problem for the 6.4L in that it can lead to rust within the fuel system, and a catastrophic repair bill: injection pump, injectors, fuel lines, lift pump, etc)
*Leaking radiator (most common in the Job 1 '08 trucks, the tanks leak where they are crimped down, plus there were many issues with leaking radiator hoses)
*Oil dilution (especially common with the DPF intact, fuel slowly raises the oil level in the crank case, and it's a good idea to keep an eye on the dipstick, and change the oil at the proper interval)
What kind of problems have you experienced with your 6.4L? We've got a laundry list of other ideas to tell you about in the December issue, non of which seems to be more common than the three issues listed above.
