NAVISTAR issued a recall on the 16523600,3800, and 4700 models

On certain vehicles, the high pressure oil line for the fuel injection system that goes from the high pressure oil pump to the right cylinder head can abrade and fail due to rubbing on the charge air cooler crossover pipe. This would result in a sudden loss of oil and if the vehicle is being operated at the time, the engine could have a sudden loss of power without warning, possibly resulting in a vehicle crash. Correction: Vehicles will be inspected and a convoluted hose will be placed over undamaged hoses. Damaged hoses will be replaced and a convoluted hose will be added.
