Ford Powerstroke Diesel Repair in Weyers Cave, VA

Over the past 4 decades there have been many iterations of the Powerstroke, each coming with its own unique problems not even related to the DEF system. The fact that there are still work trucks this old still warming up glows at 5am every morning is a testament to the design, however they all still come with their own headaches.

​

The 7.3L (1994–2003) is the legend, and mostly deserves it. What they need now is age-related: oil leaks, glow plug and valve cover harness connectors, cam position sensors, and honest maintenance.

The 6.0L (2003–2007) earned its reputation honestly. Factory torque-to-yield head bolts stretch under sustained boost and towing loads, the head gaskets let go, and coolant goes where coolant shouldn't. Head studs are the permanent fix. The EGR cooler is failure point number two. It ruptures, dumps coolant into the intake, and you get white smoke and a disappearing overflow tank. Behind both problems often sits a clogging oil cooler that quietly starves the EGR cooler of coolant flow. Watching the gap between your oil and coolant temperatures tells the story before the smoke does. Add stiction in the injectors on cold mornings and FICM voltage problems, and you can see why a well-sorted 6.0 is a great truck and a neglected one is a money pit.

​

The 6.4L (2008–2010) brought twin turbos and early DPF emissions and was one of Ford's biggest engineering failures in their history. Because of the catastrophic failure they experience we refuse to do any major repairs or diagnostics.

​

The 6.7L (2011-up) is a strong engine with two watch items: the Bosch CP4 high-pressure fuel pump, which can fail and send metal through the entire fuel system, and an emissions system (EGR, DPF, SCR) that demands healthy sensors and good fuel. Clean fuel and quality filters, changed on time, are the cheapest protection a CP4 can get. Early 6.7s (2011–2014) also had turbo bearing issues that the later updated turbo resolved.
