Common problems cited with the 6.0-liter Power Stroke diesel engine include high-pressure oil pump issues, exhaust gas recirculation failure and fuel injection control module problems. The most frequent problems with the 6.0 Power Stroke diesel engine occurred when the engine was first implemented on Ford models in 2003.
The 6.0-liter Power Stroke engine's high-pressure oil pump sometimes malfunctions due to leaking seals caused by excessively high temperatures. Too much leakage results in complete failure of the oil pump.
Exhaust gas recirculation failure occurs due to soot buildup, resulting in coolant loss and white tailpipe smoke. Fuel injection control module issues are caused by low voltage in the vehicle's electrical system.
