As far as the injector and other connector which I suspect is O2 sensor I doubt that the overfill of oil caused that. The injector looks more like grease that someone may have used for a better connection like dielectric grease. 301 is misfire on #1 which can be caused by a bunch of stuff like a bad injector, sensor, low fuel pressure or a ton of other things. Also, you do not know how overfull the oil was to begin with especially if it got to plug it would probably hydraulic the motor and that does stuff like bend rods when that happens. The manager may be right in this case but you should contact the company nationally and see if they will do anything on a goodwill gesture and have a mechanic diagnose what is causing the misfire as well. If in the case it is engine damage you will have a good case to stand on because it has been professionally diagnosed what the problem is due to whatever.
