What crazy stuff have you found in your oil?

[Kathos]

Recently I checked my oil pan that I use for draining all my vehicles and I found two copper washers and part of a piston ring. I wish my catcher was not so open so I had an idea of where/when they came out.
I wanted to hear what stories you guys had. Pictures are great.
Ps. Where do we even use copper washers inside of our xs650?

This was from my previous rebuild.

Is this your pic?

That looks like pieces of an oilpump...

I agree with 2 oil pump pieces. Whatever it came out of will solve the mystery when it freezes up or starts to squeal.

Lots of dead mice. But I think (hope) they go in while the drain pan is sitting in the shed.

The rods have a washer on each side that look like copper when worn.

And the oil pump parts should look like these;

I have a high mileage 1991 ElectraGlide and took it on a long trip. While enroute home, it developed a tapping sound and a slight miss. Rode her home and discovered I had a bad lifter, so I ordered new lifters and stuff. When I pulled my second pushrod tappet block I found a shard of bright green GLASS stuck in a oil galley! Put in my new lifters and have not had any issues since! I wondered if my 'Glide was producing it's own emeralds... but I haven't found anymore, so...

Those pieces were indeed from my oilpump. That was just a picture I had from my previous rebuild. The paragraph before was not related.
