Great reference page, always the first stop on my Google searches for answers on my trucks. My 7.3 fell victim to the injector O-ring issue and after the initial panic of pumping 3 gallons of Rotella into the atmosphere in 100 miles, the answer was here, and the knowledge shared was exactly the problem. Many thanks, Bill, from.York, NY. (NOT NYC!).....we have more cows than we have people, thank God!
