Hey guys just need some on these bearings

[Johnathan1111]

Hey guys finished my 6l it’s going good now I’m on another car I just bought with these bearings, would this cause a loud knock ? There was 2.5l more oil in it than there was supposed to be and started to knock about 1000km after no noise when I first got it so I pulled the bearing out and found this, I can’t see how this would make that loud of a knock and the piston had no movement when connected?
