Sounds like you covered everything.I once had injector tip blow off 8V92DDA.Ran fine but smoked like a Mack truck.Didn't miss at any speed,pulled fine etc..Spent over a day daignosing and found nothing.The injectors had been replaced about a month before(remans)so I automatically ruled out injectors.WRONG!I was at my wits end and began teardown for overhaul.Pulled injectors first and the 7th one out had the tip missing!WAlAHH!! IT was still under warranty too.
