If i stare at post 15 long enough..it becomes obvious the damage is happening below the piston rings , not above .The top 1/4 of cylinder looks good from here.
SO the damage is not from inlet FOD
This has to be piston skirt to cyl wall conflict..
Perhaps too fast a warm ups?
Great pics with the borescope!
