PJ,
There's more. My opinion,... the TSB 18-037-04, which is to address the white smoke issue, is for very minimal white smoke complaints. If your talking the real deal white smoke,... like I think you are, then look to injectors as the culprit. The real test,... IMHO, is to let the truck sit for a few days and start it up. If you get considerably more white smoke, then you have an injector problem. In my situation I had this and it completely ingulfed my garage in seconds. This is a long process,... from my experience. It took at least 10 days from diagnosis, to seeking approval from STAR to getting it repaired "the first time"!!!! They got approval for 3 injectors initially. Then a few days passed and all was well and then the dreaded white smoke was back. Back in went the truck and another 10 days or so and 3 more injectors. For our math majors out there, that's 6! Before I even picked it up yet another injector was bad when they tested it the morning after the last install,(that's 7 injectors)... . glad they did as I wasn't bothered with another visit and higher blood pressure. That time did it. My service writer, who has been extremely upfront with me acknowledged this is a frequent problem with the 04. 5 injectors as they have a different spray pattern and holes than previous models,... but frankly I suspect it had much to do with where I was fueling. I quit fueling at that place and began using Stanadyne everyother fillup and I have had no more white smoke at all,... ZERO. People who say it's normal are wrong. I have none and the sound of the truck and the way it takes power is totally different than previous. It is a joy to hear the pure application of power without all the pinging, smoke, and yes,... . even miss which I didn't recognize until I heard something different than what I had had previously. If I were you I'd schedule your truck for an injector test and hope you have a dealer that cares a bit about turning out a good product. That's my $. 02. Hope it helps you.
