For a humorous and oddly interesting YouTube view on what happens to bad engines in cars, see the I Do Cars YouTube channel. Come for the oil starvation, stay for the newly installed inspection ports. On a good day, he'll get some parts to sell from each core. He also occasionally goes through the process of pulling usable parts from an entire junked car. https://www.youtube.com/@I_Do_Cars
I'll add: https://www.youtube.com/@TheCarCareNut SUVs and smaller trucks are now almost universally moving to 4cyl and 6cyl turbos with iffy CVTs. The channels run by folks with greasy overalls are pretty uniform in saying these vehicles won't last like their predecessors (even the Toyotas).
How are the CVTs in these trucks iffy compared to other CVTs? There's a number of reliable auto makers using CVTs for years, such as Subaru, Honda and even Toyota on their other vehicles. CVT transmissions have been in mass produced cars longer than most of us have been alive.
