First Oil Change - What is this?!?!

loam_seeker · June 9

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.

Gasket material or sealer :dunno:

That's not making it through a filter and debris that big if stiff enough would already have your main bearings singing bad tunes.

I vote it's external crap that fell in the pan. That pretty much robot built engine isn't put together sloppy enough to drop that much gasket or sealer.

Odds are the OP wont be back. The original post is word for word and pic for pic and his/her user name is the same for another cheby forum. Joined same day same first post and other posts.

Im not saying troll, but seems that way.
