Recently we purchased a 2023 Tahoe high country with a 6.2 new (had I think 3 miles on it when they literally drove it out of the showroom for us).
Considering this is a direct injection engine I decided to put an oil catch can on it at around 500 miles. Here's what that oil catch can caught after only 3000 miles of use.

All that nasty, including whatever those solids are that stayed in the bottom, would've ended up glued to the back of the intake valves, or stuck along the intake port after mixing with EGR gases, if not for the catch can.
I'm now a believer in the need for oil catch cans on GDI engines (probably wouldn't hurt on port injected engines either, but NEEDED on direct injected ones).
