my theory is that B20's crack sleeves due to poor tuning. EDIT: poor tuning (or lack of any) that leads to detonation

yes that is a rs machine 85mm
and it had cracked sleeves? maybe the machinist didnt "measure twice, cut once"
no it's not cracked just finished putting it together

and whats those particles in the paste on top of the pistons?
