I have a 2018 F750 with a 6.7 L PS engine, and within the last couple of weeks, the engine started making harsh sounds, like it had rod knock. Also losing tons of oil, was a mystery where it went. Had it towed in, and the dealership thinks that the turbo went bad -> which led to it pumping oil into the engine -> which led to total engine failure. Has anyone else heard of this type of problem? And if so, what causes something like this ?

High crankcase pressure caused by restricted crankcase vent filter. Vehicles with high engine hours from extended idling are the most affected by this but high engine hours in general will do it. This is a known concern on 2017-2019 and later model years with a serviceable filter in the CCV oil separator. TSB 22-2380 addresses the filter and turbo diagnosis and repair... but not engine failure due to low engine oil which sometimes results.
