The owner of that truck must have been really ignorant to ignore a low oil warning for that long. I would think that the difference in oil level between a warning light and catastrophic engine failure would be pretty significant. The guy in the video seemed to think that the timing chain tensioner depended on oil pressure to maintain tension, and when oil pressure was lost the chain loosened, resulting in the Mickey Mouse ears permanently imprinted in the top of the pistons. Not sure how that would explain the grenaded rod bearing though. Either way, I guess this is what happens when you never bother changing or even checking the oil.

It won't be long before this engine goes the way of 3.0 Ecodiesel and Power Stroke.

If it does, it wasn't because it hasn't been a good engine. I think it is still around because of how good it is. GM went to the effort of updating it recently, had they planned to kill it, it would have made sense to kill it prior to spending the money to update it. That said, I am not saying that GM and everyone else doesn't spend money in a seeming moronic way sometimes. I think the EPA and politics have more play in what stays and what goes these days. It seems like the EV winds are changing somewhat from the promises made a several years ago. So maybe it will stay for a while.

The auto industry is taking a beating. Between the EPA mandates, EV being forced into the market, Union mandates, and what customers really want, I don't think the MFg's know if they need to "Wind their butt or scratch their watch".
Ram had to ditch their Eco Diesel soon after they did a complete redesign because of the black eye from the first gen ED, they couldn't sell any. Ford never committed to a diesel in half ton so they went with a existing POS engine in their parts bin and has been replaced with the Power Boost.
I don't think diesel is the right path for soccer mom use that will be in constant regen, unless they can get rid of the DPF.
