If your talking about that little half moon tapered piece on the end of the stick........... it looks like a valve keeper.. That is what holds the spring onto each valve.. takes two of them to make a circular LOCK.

Like 399gashog said, that's a valve retainer/keeper, or at least half of the pair. When you say it "runs like crap" what are you describing?

Well that explains some things.
I'm not a mechanic, but an hvac tech that works on the work trucks when we're slow.
This truck started missing severely and threw misfire codes for cylinder 1 and 2, plus random.
After testing the coils, I found cylinder one's spark plug smashed. A previous person had broken a plug in that cylinder, so I thought the impact was from that.
I figured the problem was in the valves, but management wanted me to run through many different tests before I called it lol
Ended up testing vct's and fpdm before deciding to pull a vct and inspect it. That's when I saw that keeper.
Thanks, trucks going in for some major work.
