If I'm posting in the wrong place let me know. Newbe to the diesel world so I messed up... I changed the o rings on my injectors because there was oil in the fule filter. Found the bad o ring but also replaced the o rings on all the other injectors as well....didnt watch the whole youtube vidio.... Hydrolocked my 7.3 and cranked it over twice for about 5 seconds. On the second try there was a grinding noise that sounded like rocks being slid/crushed between a metal table and a steel plate. The sound was about a second long and I did stop turning the key when i heard it. I removed the injectors again and the glow plugs and it will no longer turn over. It only clicks when I turn the key. I had 12.8v on the batteries and hooked up a charger to them so i know it's not a drained batterie. Any ideas whats wrong with it? Its a OBS 7.3.
