An old timer in a Wyoming parts yard showed me a trick for stuck injectors
I was pulling a set from a 6.0 Powerstroke in a scrap yard outside Cheyenne. This guy, must have been 70, saw me struggling and just said, 'Heat the body, not the threads, with a map gas torch for 30 seconds.' He tapped it with a brass punch and it came right out. I've used that method a dozen times since. Anyone else have a weird field trick that actually works?
