When In Doubt,THROTTLE ON
A local rural electric association has a fleet of 04-07 F350 6.0 trucks and have had injector problems with one of them. The first time it happened, the injector went out and luckily they caught it before anymore damages happened. Well, this last week, the truck wouldn't start. They thought it was gelled up, so they put some Diesel 911 in the tank and got in pulled inside the heated shop. It still wouldn't start. So they called the Ford dealership where they got the trucks from and they came and got it. They didn't some investigating and found out that the same injector was bad. But, when this injector went out, pieces floated in the fuel system from the injector coming apart and got into all the injectors in that bank and took all of them. To make matters even worse, when that one injector went bad, it dropped pieces down into the cylinder and wrecked the sleeve (Ford makes a sleeve kit just for this problem). After they pulled the cab off and got the engine apart, they also found that the head on that side is also warped. (This info came right from the Ford dealership). I believe this truck is a 2004 or 2005 with 30,000-35,000 miles on it, bone stock and rarely ever pulls a trailer. The dealership tried to tell them that all this happened because they have the wrong fuel in it. Well, once they proved what fuel was in it, they claimed it was cuz of the additives in the fuel. Again, they proved that the only additive was Diesel Power Service and the Diesel 911 so that got kicked out. Then, the guy tried to tell them that because they are running Napa Gold fuel filters, that is the problem. Somehow they claim that the spring in the Napa filter isn't right and it bypasses too much fuel causing the pressure to get so high that it blows the injectors out. At least noone fell for that one. But, I don't know if the company said they weren't gonna buy anymore trucks from them anymore or whatever, but the dealership finally said that there was a bulletin concerning the injectors torque. Sounds like the dealership is trying to keep this one hush-hush.
According to the dealership, they said that there is a bulletin out that said that the injector bolt torque should be increased from 24 ft lbs to 36 ft lbs. The lower torque value isn't strong enough to keep the combustion pressure contained in the chamber and actually pushes the injector up, blows out the o-rings and then causes all kinds of hell. They asked if they should have all trucks updated with this new torque reading and the dealership didn't really advise it. Said they'd worry about it once it happened. So, are they trying to get out of the 2 days worth of work and hope the trucks get out of warranty before they break? Or, is this nothing to worry about and it was just a freak thing?
