no oil pressure

Took off the distributer, the end of the pump shaft looked fine as did the gears. I couldn't see any signs of damage. Pulled the valve covers noticed one was not like the other.... Where's my pushrod? Bent the hell up that's where! It's broken in the pic, I did that after pulling it out. It was nearly cracked all the way through at the bend.

Also, I wouldn't say some of the other rods looked rusty, maybe scorched a little? I'm not sure but their surfaces didn't look as clean as the one pictured.
