Hi Everyone,


About 27 degrees this morning. Ran 350 miles in the snow yessterday. Got a little puff of blue smoke at startup this morning.


Is this normal? 3200 miles on truck.

I see it .... Many others too....

Wait 'till it gets down to around 0 degrees....whoa!! When I fired my truck up at 2 below leaving work Monday afternoon, I looked like I was fogging for bugs for a little bit!! Probably lasted for 20-30 seconds or so.

Both mine and my dad's do it also, as well as my 6.5 van. As smooth as the duramax is, it's still a diesel, and all diesels do seemingly-alarming things when they're cold-started in a cold climate.


I do say, we've been spoiled by how electric-feeling these engines are compared to the diesels of yesterday. Drive it and enjoy.http://www.dieselplace.com/forum/smileys/Big Smile.gif

Mine does the same thing.


I'm not going to worry about it, oil level has not moved so i don't think it oil related.

Incomplete diesel fuel burn do to cold cylinder temps at start up ....

LUCKY YOU DON'T HAVE A BIG TRUCK "DETROIT" MOTORhttp://www.dieselplace.com/forum/smileys/Ermm.gifhttp://www.dieselplace.com/forum/smileys/Evil Smile.gif

Thanks everyone. First diesel. Anything blue out of a gas engine exhaust always alarmed me in the past. 175 miles on packed snow from Seattle to Portland Tuesday morning in mostly 2 WD, and 175 miles back in 4-6" snow, washboard and ice in 4 WD. LOVE this truck.
