Are you sure it's not a freeze out plug in the back of the head. I just replaced one last week, and boy was it a pita to do in the vehicle.!

sounds like you popped what would call a core plug . Are fitted in block and idea is they pop before block cracks in cold weather. They corrode in time and can pop out.
