97 7.3 compression test ran 640 psi on cylinder 6

Truck was injector knocking and rolling smoke pretty shure I have a broke tip but before I pulled them I figured i would run compression test it ran 340-360 on all cylenders but then ran 640 on cylinder 6 and 230 on 8 it's a brand new mac tester went back to other cylinder ran 340 so it's not the tester what would cause high compression

Well I figured every thing out. The cylinder that ran high had a bad oring on the injector and was dumping fuel into that cylinder witch caused the spike in compression
