I was at my friends house checking their basement for some renovation work. I noticed their furnace seemed hot to the touch. I measured the outside panels and caught 79Deg F on all sides except the back (opposite to the service panel). This side showed a varying increase in temperature to 214deg F located about 18" from the top and dead center. We cannot easily check the heat exchanger, but I suspect it is cracked or even worst has a hole in it.

Am I on the right track?

!!!YES!!! Shut it down. A heat exchanger that is cracked or burned through is dangerous. Shut it down now. There is even a high risk of carbon monoxide entering the house through the hole
