So I pulled my throttle body to check for a plenum leak in the manifold when I found a chunk of the manifold was broken off between the two ports at the top. This is the part directly under the throttle body. I'm more concerned about where the missing piece is than the chip itself. I'll link a couple pictures.
Thanks.

How did it get chipped?

Gonna have to find that piece that chipped, cause it could possibly break a piston or something if it got into the engine...

 

I have no idea how it got chipped. I have taken the throttle body off once before and I don't remember seeing it, but then I was focused on cleaning the TB and replacing the IAC valve, so it may have been there.

 

Actually, I've seen kegger intakes that were thin in that area and gapped in that manner. The little piece is likely sitting on the intake plenum plate or has already been sucked thru the motor and ejected out the exhaust. Personally, I wouldn't loose any sleep over it.
