I’ve seen the first two videos. First one was of a 7.3 bought used that didn’t actually have a failure just high iron levels. The second was of a box truck. The third one is new to me. Well based on those three videos, if you have second thoughts about buying a 7.3 you should buy something else.

Having worked at a dealership in 1988-1992. I lived, breathed, and worked through the Fiero fiasco. Now some 35 years later some are still running. See not all had inherent problems.
having purchased a new 2005 f150 with the 5.4 3 valve, by the amount of comments and videos that truck should have died years ago. Still running strong, never apart, 130,000 miles.
all vehicles have problems, dont abuse, monitor changes, and keep up on maintenance
I currently have the 7.3 and have no regrets

I commend the OP for researching the Internet and coming here as well. Learning about what you are buying is generally a good idea.
I agree with what most others are saying... don't get too wrapped up by any individual anecdotes. You can find horror stories about any motor. Look for patterns.
From what I have seen there are very limited patterns of failure for lifters on 7.3's. It is rare enough that it would not scare me as there are limited patterns of failure on all motors.
Continue your research and make the best decision you can.

Still cheaper to tear a 7.3 down hot tank it and reassemble with new cam and lifters out of pocket than to do a fuel system replacement because of bad diesel fuel wiping out the CP4.

I maintain mine beyond what Ford recommends. 5000 mile oil changes with full synthetic. I do not worry about idling the truck, I let it idle when I want. The failures are very rare. Good Luck with your decision.

GM's 6.6 gas doesn't have the AFM of the 1/2 ton V8s but does use direct injection. I am sure a lot of buyers don't care but if you plan on owning the vehicle long term I would not want to add the headache of DI on trucks that may be idled a lot.
