Hey guys. I now have the fun adventure of tracking down why I'm blowing white smoke. Interested if there is somewhere cheapest to start while I go ahead and throw parts at this thing hoping to find it to be a cheap fix. Its a 05 2500 5.9 24valve. Smokes when I first start it after its been sitting, idles rough but only at first. If I start driving and get about a mile down the road it clears up and runs like a champ. Any suggestions as where to start is greatly appreciated. Happy Thanksgiving guys.
