Will M104 engine survive 5 seconds of overheating?

I think that I have a blown hose somewhere, causing coolant to rapidly leak out. Today, I hit the red area of the temp guage for about 5 seconds before I parked the car. After I stopped, I noted a slight amount of smoke from around the engine block, but it stopped in a matter of 3-5 minutes. Do you think that I have done permanent damage to the engine? Thanks in advance.

PS I am taking the car in to get the hose or whatever it was replaced tomorrow.
