Do you trust that modern engines are built to last over 200,000 miles with proper maintenance?
A mechanic has conducted an in-depth teardown of a 3.5L EcoBoost V6 engine pulled from a 2022 Ford F-150. The engine, which had accumulated 183,998 miles under commercial service, showed significant internal degradation.
Why it matters
The analysis offers insight into the long-term durability of Ford's popular V6 powertrain when subjected to heavy-duty commercial operating conditions. Understanding these wear patterns helps owners gauge the health of high-mileage engines.
The 3.5L engine showed evidence of a burned piston and aluminum debris causing rod bearing damage. While varnish coated internal components, the spark plugs displayed no obvious signs of failure.
The players
Ford
Ford is the manufacturer of the F-150 pickup truck and the 3.5L EcoBoost V6 engine platform.
The details
The engine was found covered in dirt and dust externally, while the overhead cams, bearing caps, and cylinder heads were coated in varnish. Investigators also noted that the bolts securing the VCT solenoids were loose during the inspection.
Timeline

2021-present: Production of the third-generation 3.5L EcoBoost V6 engine.
2022: Model year of the F-150 engine tested.
2026: Model year of the F-150.
2027: Ford models using the 3.5L EcoBoost engine.
Roadmap
This teardown highlights the mechanical challenges faced by the 3.5L EcoBoost V6 engine as it ages under commercial-grade demand. It provides a rare look at how Ford engines transition from standard usage to high-mileage, heavy-load environments.
Owners of high-mileage F-150 trucks can use these findings to prioritize preventative maintenance like frequent oil changes to mitigate varnish buildup. The inspection suggests that commercial-use vehicles may require more aggressive service intervals to hit the 200,000-mile mark.
The takeaway
Maintaining strict service schedules is critical for turbocharged engines used in demanding commercial environments. Regular inspections can help catch loose components or early signs of internal wear before they lead to catastrophic failure.
