I recent developed a problem with my 2005 F350. The engine is the normal 6.0L and whenever I start it, you see an excessive amount of white smoke coming out of the exhaust. The engine sounds fine, normal hard cold start chugging for Alaska (-35 degrees) and no check engine lights of codes on me OBDII reader. There is a strong exhaust smell. Not sure if its normal as I've never ran a diesel in this kind of temperatures or whether it could be the head gasket starting to go. Any ideas? The exhaust color is a thick white.
Are you plugging it in? Does that change anything? GPR and GP’s working properly?
On a side note regarding cold starts, have you tried Archoil 9100? It will change the way your truck starts and runs…seriously! My buddy has an 04 6.0L 130k, typical hard start every morning. I was changing my 7.3L oil and had been running it and he was giving me crap about snake oil . So I gave him the extra bottle I had and said here, Let’s change your oil and put this in and we’ll see if it changes anything in your truck, I’ll give you the bottle. What do you have to lose? So we changed the oil dump the full bottle in and he forgot about it. He drove to the airport the 2 days later with about 120 miles worth of running the Archoil, truck sat for 6 days in near zero temperatures. He gets in the truck turns the key and starts perfectly-no grumbling, pissing or moaning just a beautiful idle. He swears by the stuff now...

The GPs seem to be working properly, but do shut off pretty quickly. If its really cold (below zero) I just prime them by cycling them a bit before turning the truck over. I will definitely try to Archoil9100 if I can find it. Amazon doesnt ship liquids to Alaska in winter time so I will have to find it here. I'm more concerned about a possible head gasket or injector issue that is going to cause a bunch of repairs. I was recently in an accident and my wife's car died so I am paying for three trucks on a military enlisted paycheck. Obviously not enough and am trying to avoid jumping the gun if there's a simpler explanation.
Are you plugging the truck in? Does that help? I’d grab your meter and make sure your GPR is actually working at 12V. They should cycle for almost 2 minutes in your cold temperatures. Let’s check the easy, cheap fixes off the list first.

The glow plugs continue to run after the light goes off. They'll run up to 120 seconds, even after the engine starts, completely controlled by the computer, so no need to cycle the key multiple times. Cycling multiple times actually increases the chance of running a plug longer than intended, breaking it, and having it drop into a cylinder. The engine is coming out when that happens, very bad deal.
Are you running a 5W-40 or 0W-40 diesel oil in it?
You need to check the alternator and FICM output with an OBDII scanner like one of these, one of these is the only things that will stop you from pissing away cash blindly by guessing because they give you real information to base decisions on: https://www.ford-trucks.com/forums/1...eral-info.html
