Help needed pistons

[Ace101]

Hi new to the forum , I’ve got a 172 that has spun a bearing on number 3 🤦🏼‍♂️ , I’ve stripped It down and amount other things I’ve found some putting on 2 pistons, see pic. Not sure how this has happened would you say it fecked? Think it my course pre ignition but not sure?
thanks I’m advance 😃
