#4 Yes, mine looks exactly the same and I was also thinking, "why the heck aren't these threaded in the same depth?!?!?!" First truck with torsion bars, so thanks for posting the question and double thank you to everyone who responded and explained what is going on here!

Good Morning! First post here...been running a Dodge diesel for the past 13 years. Happy to be back in a Chevy (my third). I searched the forum and couldn't find anything on the topic. My apologies if I missed it! Please just paste a link to point the way and I'll move the question there. Anyways, I just did my first oil change on the new truck at 500 miles. Here's what I found in the bottom of the oil catch pan (which was brand new and spotless...). Any ideas what this could be??? More importantly, what it could have come from? Again....new motor with 500 miles, so this is during break in. It was about 1/2inch long (pics show two pieces, after I tore it to see how it came apart), and seemed to have layers....honestly, it looked like shale, but was bendable. The only external influence I could think of is that perhaps it fell off of my old oil filter wrench. Otherwise, I have no clue. Wanted to see if you all had any ideas. I'm no professional mechanic, but I've been wrenching for about 20 years....stumped.
