Reliability Only Goes So Far
While Ford’s 6.8-liter Triton V10 isn’t exactly an exciting engine, it’s generally regarded as a reliable workhorse for heavy-duty applications. That’s why, when this particular example destroyed itself, Eric from I Do Cars set out to find what could have caused such a catastrophic failure through a teardown.
The engine was sourced from a 2018 Ford E-450 cutaway van, though details such as the VIN and mileage were unknown. It was the two-valve version rather than the more performance-oriented three-valve configuration. The Blue Oval once previewed a quad-cam V10 in the Shelby Cobra Concept, which some may recognize from the 2005 film xXx: State of the Union, but the setup never made it to production.
A Triton V10 With Exit Wounds
Right off the bat, the Triton V10 showed several large exit wounds, indicating that the failure was violent in nature. The cylinder head didn’t show extensive damage, aside from a roller finger follower that had come out of place. However, the presence of oil varnish suggested the engine may have suffered from infrequent oil changes—an issue that can severely compromise lubrication and the proper operation of moving components.
Moving to the block, four of the ten piston crowns were missing from their respective cylinders. Many of the resulting fragments were found in the oil pan, including a bent wrist pin. Eric also noted discoloration on the components, a telltale sign that it had been exposed to excessive heat.
Neglect Writes Its Own Ending
As such, the components likely overheated due to increased friction caused by inadequate oil lubrication. What makes the failure particularly notable is that the engine was positioned partially beneath the cabin. That proximity means any early warning signs—such as unusual noises or vibrations—should have been noticeable early on. Given the extent of the damage, it appears those warnings were ignored, ultimately leading to the engine’s demise. Eric bluntly described the driver as an “idiot.”
In other words, failures like this were unlikely the result of a design flaw, but rather the product of neglect—particularly given that the two-valve Triton V10 was engineered with reliability as a priority. The engine was discontinued around 2019, with propulsion duties taken over by the larger 7.3-liter Godzilla V8, which is also used in the Super Duty pickup lineup.
