Major Ecoboost repair, long delays
My daughter parked her 2013 F150 Ecoboost with about 140,000 miles on it back in mid-May. When she started it back up it would barely run and was very rough. To make a long story short it was parked...

Wouldn’t that primarily be the function of the block and cooling system? Seeing as it’s been around for at least 10 years and is still being sold - seems like it has a worthwhile track record.
bad luck for early adopters. never seemed practical to me. too much heat and stress for small engine.
Name the engine and I’ll point you to a post about someone that had a major problem with it; that doesn’t make it “impractical”.
Reality is somewhere in the middle.
A smaller block putting out the same HP, has more heat and stress per unit of mass/volume in the block but as you say, the engine has been around for 10yrs with no sign of it going away, so probably not a huge issue statistically.
I suspect a lot of it depends on how it gets used.
Vast majority of 1/2 ton trucks never tow anything or tow very rarely and not at max ratings. On a grocery run, you aren't asking much of the engine, so it never gets that much stress. Even if you stomp on it in a drag race, the extra load doesn't have enough time to overheat anything. Those engines are probably fine for 250k miles with just normal maintenance.
But for those relatively rare folks who do a lot of towing near/at max ratings, particularly mountain towing, it is a lot more stress. Particularly if the owner is the type to just put the hammer down and not pay attention to the gauges, I could see them easily over stressing the engine and shortening the engines life.
