Should I total my Jeep or get it fixed?

I have a 2002 Jeep Liberty with the 6 cylinder engine. My wife was out running errands, and at one of her stops, the car would not start. I came to pick her up (and try to start the car). I was able to get the Jeep started and drove the short distance home.

I suspected plugged injectors based on how the car was running: refusing to idle (just dieing), very poor accelleration, no power.

I pulled each of the spark plugs only to discover that the plug for cylinder #2 had been TOTALLY flattened. It looked like it got hit VERY hard with something! Also, the plug was full of oil.

I purchased a micro camera to snake into the cylinder to see if I could see if there was any damage to the cylinder. From what I could see (very difficult to navigate around in there) the cylinder walls themselves appear smooth. The one valve I could see looks like it got hit with a ball peen hammer - dented like crazy.

My question: is it worth pulling the head to insure that the cylinder walls are not scored? NOTE: this model year is an all aluminum block. I don't want to spend the money to get ready to repair a broken rod or valve only to find out the entire engine is shot. What do you recommend?
