2020 6.2L: misfires, lifter issues and engine replacement

[Fless]

If it helps, the 2020 owner's manual states to change the filter when changing the oil (at least once a year).

ok, so everyone shows up to tell me i'm an idiot for not changing the filter often enough. i will be changing the oil filter with the oil from now on. my wife put a lot of miles on this car, so the oil filter has been changed at least once a year, albeit not at every oil change.

what about what i actually posted about - the 14k quote for replacing the engine? i'm legit shocked that the solution to the first clear sign of a problem is to replace the entire engine, rather than replacing some components, e.g. lifters.
