Five Common Problems With the Ford Powerstroke 6.0L Engine

If you drive a 2003 to 2007 Ford Superduty Diesel truck with the 6.0L Powerstroke engine, we hate to say it here at Moose Jaw Truck Shop but you’ve probably had some problems with it. A tough and reliable truck overall, Ford missed the boat on some of the features in the Powerstroke engine, and we fix the following five problems for our customers all the time.

1. Head Gasket Failure

The problem with the Powerstroke’s head gasket boils down to the torque-to-yield or TTY head studs. Many Ford Superduty owners have made aftermarket modifications to their diesel trucks only to find that the TTY head studs cannot handle the additional pressure under the head gasket. Once the TTY head studs fail, the head gasket fails, too.

2. FICM Failure

Fuel Injector Control Module is what FICM stands for, and this module has a history of failing in the Powerstroke engine. The FICM is responsible for supplying solenoid voltage. The two solenoids for which the FICM supplies the voltage control how much oil flows into the fuel injectors. Engine heat and vibration wreak havoc on the FICM, causing it to get too hot, as well, and fail.

3. Oil Cooler Problems

The oil cooler in the 6.0L Powerstroke diesel engine can also cause problems. Oil must be cooled much more in the Powerstroke engine than in other diesel engines, so Ford equipped the 6.0L diesel engine with an oil cooler that is liquid-on-liquid. Dirt and debris clog the oil cooler which, in turn, causes the EGR cooler to fail, as well.

4. EGR Cooler Failure

Aside from the oil cooler failure discussed above, the EGR cooler in your Ford’s Superduty engine can also fail because it is clogged. This increases the temperature of the EGR cooler causing it to fail and, eventually, causing your head gasket to fail, too. EGR coolers can also leak engine coolant into your Ford’s exhaust system and you’ll end up with white exhaust coming out of the tailpipe.

5. EGR Valve Failure

Finally, the 6.0L Powerstroke engine is also known for EGR valve problems. This valve is responsible for regulating the vehicle’s exhaust gases that are introduced back into the engine. Soot from the exhaust can clog the EGR valve and cause it to fail. If the EGR valve sticks open because you have a poor quality of diesel fuel in the engine, you’ll notice engine performance issues with your Superduty truck.
