Probably a dumb question but i have a stock 04.5 lly and on cold days when i start it it smokes for about 5-10min after cold start. Is there an issue or just a typical thing to do below 40F?

My truck does it also, I have talked with a few mechanics and researched my butt off. It is normal. I do have one bad glow plug and have been told that may be the problem.

Totally normal. You should see em smoke when it gets to about -20 and high idle!
