The 6.4L Power Stroke replaced the 6.0L in the 2009 model year. This new design has experience fewer issues and problems than the 6.0 Power Stroke. Common problems with the 6.4 Power Stroke are similar to previous Power Stroke engines, but on a far smaller scale. The fuel efficiency is a lot worse. Some may have issues with the head bolts failing, EGR and EGR cooler failure, Oil cooler failure, Fuel Injection Control Module (FICM) Failure, Injection Control Pressure (ICP) Sensor failure, Injection Pressure Regulator (IPR) Sensor failure, Hydraulically Actuated Electronically Controlled Unit Injector (HEUI) failure, High Pressure Oil Pump (HPOP) failure, Turbocharger Lag, Sticking VGT Vanes, Turbocharger Failure, Wire Harness Fraying and Damage, Oil Rail and Plug Leaking, and Coolant leakage.

The 6.7L Power Stroke is the first Power Stroke diesel engine developed by Ford. After so many problems with the International/Navistar developed engines, Ford changed directions and brought it's Power Stroke development in house. At this point, we've seen plenty of the 6.7 Power Stroke's in the shop, but mostly for maintenance. One issue we've found with the 2012 and 2013 6.7L Power Stroke powered Super Duty is a definite shake that occurs when towing heavy loads that within Ford recommended capacities. We've experienced it with 2012 model year F350 in single and dual wheel axles as well as 2013 single rear wheel axles. The shaking in these cases was caused by the angle front to rear of the rear-end. Ford may have this issue in their computers by now. We've been told that shimming to change the pitch does take the shake out, although you shouldn't expect 100% of the shake to disappear. Ford advised at the time that it doesn't risk damaging the vehicle. Your call. More to come...
