Common 6.0L Powerstroke Issues

Do you have a problem with your 6.0L Powerstroke engine? You are not the only one. There are a number of common issues associated with this type of engine. If you have a vehicle with this type of engine, your engine trouble may be caused by one of these failures.

Oil Cooler

Sand that remains in the oiler cooler of the 6.0L Powerstroke from the manufacturing process commonly causes the oil cooler to fail. Using poor quality motor oil in the engine may lead to accelerated oil cooler failure.

EGR and EGR Coolers

The exhaust gas recirculation (EGR) valves, used on the engine to lower emissions, can fail after a build of soot when the EGR coolers do not work properly. White smoke, which is actually escaping steam, in the exhaust is a sign of failure.


The fuel injection control module (FICM) can burn out quickly on the 6.0L Powerstroke engine due to excessive heat and vibrations. Stalling and a rough ride are signs of FICM trouble and demand attention.


The swash plate style pump of the 6.0L’s high pressure oil pump (HPOP) is known to have many issues ranging from the leaking of seals to even a complete malfunction.

ICP Sensors

Some 6.0L Powerstroke engines were shipped with faulty injection control pressure (ICP) sensors. Replacement ICP sensors typically experience none of the issues associated with the original sensors.

Oil Rail Plugs

The high-pressure oil rail’s plugs have faulty O rings and can lead to stalling or difficulty in starting the vehicle.

Coolant Leakage

The degas bottle has a leakage problem due to faulty seams.

HUEI Sticking

The hydraulically actuated electronically-controlled unit injector (HUEI) in this engine type can become stuck more easily than with other engines. Low quality oil and fuel can increase the chance of the HUEI sticking.
