What is 6.4 powerstroke?

The 6.4 Powerstroke is a diesel engine produced by Ford Motor Company. It was introduced in 2008 as a replacement for the 6.0 Powerstroke and was used in Ford Super Duty trucks until 2010. The engine has a displacement of 6.4 liters and features a twin turbocharger setup for increased power and efficiency.

Although the 6.4 Powerstroke was known for its strong performance, it also had some reliability issues, including problems with the high-pressure fuel system, turbocharger failures, and exhaust gas recirculation (EGR) system issues. These problems led to a less-than-stellar reputation for the engine among some diesel enthusiasts.

Overall, the 6.4 Powerstroke is considered to be a decent engine when properly maintained, but it does require regular maintenance and attention to prevent potential issues. Some owners have successfully modified and upgraded their 6.4 Powerstroke engines to improve performance and reliability.
