* Head gasket failures: A common and costly problem.
* EGR cooler failures: Could lead to coolant leaks and engine damage.
* High-pressure oil system issues: Including pump failures and injector issues.
* Turbocharger failures: While not exclusive to the 6.0L, it was a frequent concern.
* Fuel system problems: Including injector issues.
Later production years saw some improvements, with Ford implementing various fixes and updates. However, even later models aren't entirely immune to problems.
In short: The Ford 6.0L Power Stroke is *not* considered a reliable engine, especially compared to other diesel engines. While some owners have had positive experiences (often with well-maintained and proactively repaired engines), many have encountered expensive and recurring repairs. The potential for significant repair costs should be a major factor when considering a vehicle with this engine. Thorough pre-purchase inspections are crucial.
