Puff of white smoke after idling at stop lights
During normal driving I'm getting a puff of white smoke each time I take off after sitting at a stop light for a few seconds or more. Just started a couple days ago. I'm running the economy tune... last week was still running the tow tune from towing our Toy Hauler the previous weekend. Truck has 60k miles and has lived an easy life. I only started towing the Toy Hauler a few months ago. On cold starts (high idle) I think I'm also seeing some white smoke, though not much.
No engine lights, no loss of power, except for these puffs of white smoke. If it was a normally aspirated gas motor I'd be guessing valve guide seals... but these diesels seem pretty complicated to me. What do you think it could be?
I'm really trying to decide if its critical to get it to the dealer now... or safe for a couple more weeks. I've got a 2-day camping trip planned for the weekend after next. Once we get back from that I've got nothing planned, so I would love to wait until then to let the dealer have it.
Thanks for your input,
