Actually, it looks like a very small roll pin. Also, full of rocks too!!

My personal truck, parked in driveway every night.

And I'm very careful about oil changes, never done by anyone but me since I got it.

Not a normal looking rock, sort of polished and extremely hard. Has me puzzled.

This is a dump truck and I do go in a bunch of stone yards on a regular basis. When taking the valve cover off, I always make sure to spend some time with blow gun up there, but maybe someone in the past wasn't so careful?? That was my first thought.
