changing o2 sensor

I need help! I am trying to replace the o2 sensor on my 1982 280e. I can't get the old one out. I am using a special o2 socket with a 1/2" drive breaker bar but I can't budge the thing. I think it is the original sensor--not replaced in more than 15 years. I have already soaked it in liquid wrench and have also tried heating the part of the exhaust, but no luck. I am afraid I will strip the outside of it if I use much more force. Any ideas would be much appreciated. Also, will I cause any damage if I just leave it there (already cut the wires), and run the car in open loop?
