How good is the Ford 6.4 diesel engine?

The Ford 6.4 diesel engine, also known as the 6.4L Power Stroke, has a mixed reputation in terms of reliability. While some people swear by the engine and consider it a significant improvement over its predecessor, the 6.0 Power Stroke, others have had negative experiences and consider it one of the least reliable Ford diesel engines.
One of the common problems with the 6.4L Power Stroke is leaking radiators, especially in the early model-year trucks. Ford issued several technical service bulletins on this issue, and while there are aftermarket options available, the original radiators can be expensive to replace.
Another issue is poor fuel economy, particularly when driving in traffic or at slow speeds. This is mainly due to the diesel particulate filter’s need for fuel.
The 6.4L Power Stroke also has a reputation for various other failures, including problems with the high-pressure fuel pump, cracked pistons, and clogged diesel particulate filters. These issues can lead to significant engine damage and costly repairs.
Despite these problems, some owners of the 6.4L Power Stroke have had positive experiences and are satisfied with the engine’s performance and reliability. However, it is important to note that the engine’s reliability is generally considered to be lower compared to other Ford diesel engines.
In conclusion, the Ford 6.4 diesel engine has a mixed reputation for reliability, with some owners reporting positive experiences while others have encountered various issues. It is recommended to do thorough research and consider the potential problems before making a decision about this engine.
