I have a 02 Dodge Ram QC auto and I am new to the CTD but not to the Dodge Ram pickups. I have owned 4 gassers and they all have served me very well each going over 150k. I love the power of the CTD and have been lurking here since I bough my truck in August to learn as much as possible. There seems to be a vast wealth of knowledge on this site. <br><br>I have noticed when I start my truck when its cold I have seen a small puff of black smoke when I start the truck. I have been told that is normal. I started my truck this morning and it smokes white for several minutes. <br><br>What could be the cause of this Smoke and why the change from black to white smoke? I have not noticed any change in the way the truck runs or loss of power.<br><br>Any reason to be worried?<br><br>Thanks from a noobie!!<br>

 

You didn't have the block heater plugged in did you?<br> That will happen sometimes when its cold, excess unburned fuel can be black and sometimes white I see this at some truck stops when they first fire up.

 

No block heater used. That what makes this so strange. It was warmer today than it has been and I have never seen this before even when it was much colder.

 

Happens all the time, Sometimes you notice it a bit more than other times. Just the condensation that builds up inside your exhaust system as it cools will add to that as well. <br> Unless it keeps doing it long after it has time to reach operating temp I would not give it a second thought.

 

Thanks for the reply. Just wanted confirmation from someone with more experience with the CTD. I know this, after driving my CTD for the last 3 month I will never go back to a gasser!!! ;D ;D ;D
