If you have a stuck injector your egts would be through the roof and you would likely have blown a turbo by now. I haven't worked on the 8.3, but many diesels have tubes that deliver the fuel to the I jectors. In the Cummins 6.7 when you change injectors if you don't correctly install the pass through fuel tubes which are in the head they will leak and end up in your oil. I don't know how that would end up in your exhaust. I would find a different mechanic. Atf in fuel won't hurt much in an older diesel but it rarely if ever will fix a stuck Injector. I would check your fuel lines, crank case breather, use an infared thermometer on exhaust header to check for stuck injectors just in case.
