Default Can anyone ID this o-ring?

Tonight I was cleaning up parts for a rebuild. Parts were: Roller Rockers, Heads (with springs installed), pickup tube, oil pan, windage tray, oil cooler bypass (holley pan).

I found this in the pan when I was cleaning up. I'm 99% it was not in there before I started working.

Color is blue. Top shape is "trapazoid-ish. Bottom is flat. 10MM socket for scale

Same thing I'm thinking. Check your Valve Cover Bolts see if one of the rubber seals is missing.

valve cover bolt seals have more height and shape to them. This is rather flat.

You ever seen one with the center broke out? That's how it falls off the bolt.
