At the time, the 7.3L Powerstroke was the most powerful engine ever built by Ford and Navistar with improved torque and 275 of horsepower. However, GMs Duramax LB7, as well as the common-rail Cummins 5.9L were reaching 300hp or more. In addition, new legal and regulatory requirements including more stringent NOx emission standards were on the horizon. As a result, it quickly became clear that the 7.3L wasn’t going to survive.
Ford and Navistar knew that a complete overhaul of the Powerstroke engine was required. They also understood that an engine redesign of that magnitude would require years of analysis, R&D and manufacturing time. That’s why they began planning for the release of the 2003 Powerstroke 6.0L all the way back in the late ‘90s when the 7.3L was riding high.
The 6.0L Powerstroke made the 7.3L appear to be outdated because of these new features:
Unfortunately, a number of the 6.0L “upgrades” proved to be a disappointment. Problems started adding up. Issues with the EGR, oil cooler, head gasket, high-pressure oil pump (HPOP) and a sticky turbo began to plague the engine.
However, it wasn’t a total disaster for the Powerstroke 6.0L. The sturdy short-block was very durable, it had extra engine power and quick responsiveness and people also liked the 5R110 automatic transmission option which was highly praised for its efficiency and its ability to handle a huge amount of torque.
The Powerstroke 6.0L has been beaten down by people inside and outside the diesel truck industry. Some of those opinions are deserved, others are not.
While it’s true that the 6.0L Powerstroke doesn’t have the durability and problem-free longevity, of a Duramax or Cummins, if you take good care of it with regularly scheduled maintenance and upgrades where recommended, it can be just as reliable as those two engines.
