May 9, 2024Table of Contents
Choosing the right Powerstroke engine can feel like navigating a maze of options, especially for diesel enthusiasts well-versed in the industry. This comprehensive guide unpacks the 6.0L, 6.4L, and 6.7L Powerstroke engines to determine which reigns supreme. From reliability to performance, we’ll explore each engine’s strengths and weaknesses to help you make an informed decision.
How Reliable is the 6.4 Powerstroke?
When the 6.4 Powerstroke engine debuted in 2008, it captured the eyes of 6.0L Powerstroke enthusiasts, promising an improved design for reliability and better performance. It was also the first Ford engine to address newly introduced emissions standards. Known for power and not longevity, the 6.4 powerstroke has a mixed reputation for reliability. While some have praised the engine’s durability and power, others have noted common areas where it left more to be desired. Remember that the 6.4 powerstroke was the first engine to feature an advanced emissions control system, including a diesel particulate filter (DPF) and exhaust gas recirculation (EGR) system. With any new tech introduction, the complex systems were often linked to reliability challenges due to clogging or failure.
What sets the 6.4 powerstroke engine apart in its design is the design of strong components like the bed plate and some of the strongest OEM rods used in a light-duty diesel engine. Did you know this engine features a high-pressure fuel pump with 20% more flow than its rivals during its production years?
To get the most out of your 6.4 Powerstroke crate engine, don’t forget about regular maintenance to keep your engine reliable. With diligent maintenance and attention to known issues, the 6.4 Powerstroke engine can provide reliable performance and longevity, reaching well over 200,000 miles in many cases. To maximize your time on the road, the 6.4 Powerstroke offers a variety of aftermarket solutions and parts.
How Long Will a 6.4 Powerstroke Last?
The longevity of a 6.4 Powerstroke engine can vary depending on several factors, including maintenance, driving conditions, and usage. While pushing back your oil changes can be tempting, the more you ignore caring for your engine, the more likely it is to miss major issues that can cause engine failure. A 6.4 Powerstroke can average 200,000 – 300,000 miles (322,000 – 482,000 km) with maintenance.
If you are considering a remanufactured 6.4 Powerstroke engine, keep in mind that the reman process’s quality should be considered. Opt for a reputable company with experience in remanufacturing diesel engines. A thorough remanufacturing process, including disassembly, inspection, machining, and reassembly with high-quality parts, can result in an engine that performs like new and has a long lifespan. Our experts at DFC Diesel can help you pinpoint what you are looking for in your 6.4 Powerstroke and engine upgrades, like the Speed of Air Hyperformance Pistons, that can give you more power and durability for your vehicle.
