Power Stroke is a branded diesel engine that has been produced for Ford vehicles. Ford Power Stroke engines may be found in the vehicle manufacturer’s Super Duty trucks, Econoline vans, Excursion SUVs, and their LCF commercial vehicles. The engine started being produced in 1994.

Until 2010, the Ford Power Stroke engines were manufactured by Navistar. In that year, Ford decided to make the engines at their Mexican production facility. These 6.7 liter Power Stroke engines are now primarily utilized in the Ford Motor Company’s full sized pick-up trucks in the United States.

It was in 1994 that the 7.3L Power Stroke diesel was initially unveiled. The Power Stroke is a direct injection engine that is electronically controlled. It has a 104 mm bore and 106 mm stroke that creates a displacement 444 cubic inches. Its compression ratio is 17.5:1 and weighs about 925 lbs.

The 7.3L Power Stroke was used until the middle of 2003 when it had to be replaced by the 6.0L Power Stroke due to the 7.3’s inability to meet the new emission requirements.

The 6.0 has been known to experience blown head gaskets and eventually cracked cylinder heads attributable to the fact that the 6.0 only had 4 head bolts per cylinder and the “domino effect”. Many of the issues with the 6.0 started with the fact that Ford used sand cast molds In many cases the residual sand would clog the oil cooler, which would take out the EGR cooler. When the EGR cooler went bad, it would pump coolant thru the engine. When enough coolant got into the engine, it would stretch those head bolts allowing the head gaskets to blow. These Ford trucks got somewhat of a bad reputation because of these failures, which were due to improper service bulletins. it was not standard procedure to replace the oil cooler. There were many repeat failures until the company used new concepts in repairing the trucks.

In 2007 Ford presented the 6.4 Power Stroke. This new edition was necessary again, because of emission regulations. In spite of the stricter regulations, Ford was able to increase horsepower with the 6.4 Power Stroke. The 6.4L has had one recall due to the potential for flames to come from the tailpipe. A PCM recalibration is necessary to eliminate the possibility of these high exhaust temperatures that combine with other conditions to create what is known as the thermal effect.
