My 2013 6.8 L V10 at work swallowed a valve when it was 2 years old. Was just a few hundred miles over warrantee and Ford refused any goodwill offer. We installed a new ford crate motor, and not even 2 years later that one also swallowed a valve.
Closer inspection revealed that one of the rocker arms had side to side play, and caused it to damage the valve retaining mechanism. Third motor is so far so good. We run our work trucks hard at my job, but use Motorcraft semi synthetic and Motorcraft filters once a month.
On a sidenote, our 2009 Ram 6.7 Cummins just put a rod through the block toward the back on the driver side, but it ran 490,000 miles in those 8 years!
