7.3 Powerstroke Years to Avoid: The Mystery

Diesel engines are engineered for heavy-duty use. Any weak point will cause problems and create long-term issues. Ford has been the legend in making heavy-duty vehicles for more than a century.

A new generation of 7.3L Powerstroke engine took place in the hearts of young people. However, the OBS (old body style) truck was discontinued in 1997, and soon after that, the next-generation truck was announced as a Super Duty model

Super duty was also equipped with a less complex and highly reliable rugged structure. Also, 7.3L Powerstroke was added with the later generation. But, due to some noise issues and emission controls, Ford had to change engine equipment. 

Powdered metal rods (PMR) are weak equipment for a heavy-duty truck. The early 2001 super duty models came with these connecting rods. The replacement of a forged rod from the engine hit hard among truck enthusiasts. 

Well, then Ford decided to discontinue producing 7.3L with emission control and other types of injectors. This is why remember model years of 2001 from 2003 to avoid purchasing a 7.3L Powerstroke.
