I pulled the oil pan off to see what was going on below. Everything looks good and cranks smooth, but I found these 4 clips/retainers attached to the magnet in the bottom of the pan. I apologize up front for being inexperienced, but I have no clue what these are? Is it a sign that the engine needs pulled and completely rebuilt again? Is this something I can fix while the engine is still in? I really appreciate any input you can provide. Thank you.

Greetings fellow club member!
I hate to have to tell you this--but I do believe it would be in your best interest to tear the engine down again. what you have found in the oil pan are broken wrist pin retaining clips. This type of clip is most commonly found in agricultural or industrial type engines employing "full floating" wrist pins. Most automotive engines use wrist pins that are press fit to the connecting rod and do not use retaining clips of any kind.
