I had a closer look at the rings and the broken ring has a concave wear patters on the axial face of the ring and you can clearly see the sides are shiny (high spots) compared to the center were ist not being touching the piston as is darker (carbon)
The good rings are not as severly worn as broken one but show slight concave wear.
Piston grooves dont show any wear though.
Not sire what would cause wear as such besides being hammered by detonation? Rings rotating to much or to fast? Never realy heard of this or why it would happen.
Rings maybe have maximum of 10-15000km so the wear seems quite excessive
Also confirmed rings gap and its 0.42 mm so seems plenty of anything on the high side
