Bad metal on metal type noises...

I was driving the car, saw a red light come on, "check guages" ... look down, 0 oil pressure, temp was fine though from what the guage said, less than 210. Pulled the car over immediately to see coolant flying out of the overflow and a loud knocking type sound from the engine.

Ask me more questions about it and I'll get back to you tomorrow, have had a rough day and I'm done typing.
