a little puff of white smoke on take off?

[SuperMidget]

just picked up this truck yesterday and noticed it only does it at the top end 2nd gear just before i shift to 3rd from what i can tell when getting up to speed i blow a small ammount of white smoke, thats the only time it smokes at all, 1st diesel i've owned so thought i'd ask around if thats normal or anything i should be concerned about

First off let me say I am not expert by any means but white smoke out of our trucks when they are first warming up on a cold morning is normal expecially if you didnt plug it in so you could be getting it from that if you starting it up and taking off right away. However saying that if your truck is warmed up at all it should not be smoking unless its black. White smoke (not blue) usually means you may have an issue with an injector or two.

A little more info on the specifics like rpms and operating temp will help with getting more speicific info.

it could be a puff of blue smoke, its so thin its hard to tell in the mirror since it has only done it a few times while accelerating
