Do you know what years are ford diesel engines to avoid? Well, it’s the ford super duty 6.0L Powerstroke from 2003-2007 and the 6.7L Powerstroke from 2011-2014.
The ford diesel engines are known as Powerstroke engines. These 6L and 6.7L is diesel engines had some significant issues. Thus buyer needs to be aware of buying these Ford SuperDuty diesel trucks.
But why you should avoid them is the primary concern. Don’t worry at all! We will discuss all the detailed information about the worst diesel engines that you need to avoid.
So without any further talk, let’s jump into the main topic.
The 6.0L Powerstroke from 2003 to 2007 ford SuperDuty diesel truck has had significant issues from the very beginning. Most of them originated from the manufacturer’s factory. That is why it is always better to avoid these year models of Ford diesel engine trucks.
However, one of the main reasons behind these problems that worked as a contributor was the EGR emission system. The 6.0’s are commonly known as six leakers. Problems like TTY head studs or head gasket failures, oil cooler, EGR cooler problems, HPOP, FICM failure, and many more.
Similarly, the 6.7L Ford SuperDuty from 2011 to 2014 is another ford diesel engines to avoid. EGR failures, turbo failure, and emission systems adding multiple failure points are common issues of this Powerstroke engine. In addition, this engine also has injection pump failure, ETG sensor failure, cooler clogging, etc. issues.
Now that you know what ford diesel engines to avoid, you should know why to do so. Some common diesel engine problems in Ford trucks are illustrated below-
The FICM is located beside the diesel engine. Sometimes the control module can get overheated or fail due to excessive vibration or heat from the engine. The FICM failure can cause no start, rough start, or running condition.
Besides, the capacitors o the fuel injection control module can get damaged by the negative impact of cold weather, drowning excess voltage. However, you can locate a faulty control module using a scan tool. Also, look at the PID data while checking or scanning the fuel injection control module.
The torque to yield or TTY head studs are rigged with the 6.0L ford diesel engine. Adding a tuner sometimes can cause the head gasket failure. An auxiliary tuner can increase the cylinder head pressure beyond the torque to yield capability.
However, after removing the TTY from the Powerstroke engine, it becomes unable to be re-used. And you must replace the TTY in the machine right after removing it.
The EGR cooling system problem is one of the most common ford diesel engine problems experienced by the owners. The EGR cooler problem mainly arises from the higher temperatures in the oil cooler.
Coolant enters in a small amount when the EGR oil cooler gets clogged. And the clogged cooler is the main culprit behind the potential damage, boiling coolant, and high temperature.
LIKE THE EGR COOLER, the EGR valve gets clogged due to excess soot. Sometimes the problem can arise because of poor fuel quality.
The 6.0L diesel engines most commonly have high-pressure oil pumper failure in them. The oil pump is a complete failure in the 6.0L Powerstroke. It also has leakage issues.
You can replace it if the high-pressure oil pump in your diesel engine fails. Moreover, you should also check the HPOP screen while replacing the HPOP.
