If there were one engine that plagues the mid-size diesel world, you would have to say that it is the 6.0L Power Stroke. The 6.0L came into existence because the EPA demanded tighter emissions laws for diesel engines. Even though the 7.3L was branded as the reliable workhorse for Ford, it would never be able to pass the tighter emissions laws that were going to come into effect for 2004.
