blue smoke when cold

I just bought a 96 f250, I love it and it seems like a good truck everything seemed to check out and it was a nice truck. He always parked it in a heated shed so when he started did not notice anything. But when I started it after letting it sit about five hours last night not to mention we had a wind chill of -15. When I started it it blow more smoke than expected and had kinda a blue tint to it. Is this something I should worry about?

As long as the smoke goes away after a few minutes of warming up, then you are fine. What you are seeing is unburnt fuel. It's just a result of the engine being cold. My truck smokes quite a bit when it's below 10 degrees outside and I first start it up. Takes between 5 and 10 minutes to warm up enough where it isn't smoking anymore.

I was away on biz in Toronto the other nite and it was nasty cold and the truck was unplugged (94 psd). It took a couple attempts to get it running and when it did it loped and chugged and blew lots of bluish tinted smoke but once it warmed up all was well so you're experiencing something I suspect all psd's are subject to in the unplugged cold extremes.
