Sorry I confused you but, I already know what the problems may be, and once I saw the anti-freeze/tailpipe, I did not crank it again, and had it towed to the dealership. I was just trying to figure out if I did something that caused the gasket/head to let go.
Maybe the head gasket was already damaged and leaking, but because the water pump wasn't working at 100%, it just caused rough idling, then, the increased pressure of the new/properly functioning water pump caused the gasket to give way completely. I still can't figure out why the engine wouldn't warm up though.
