I have a 2003 that smokes alot when I start it up. During the summer it would always belch white/blue smoke for a couple seconds during a cold engine start up. This morning I went to start it up, 30 degrees (I can't plug it in since I live in a condo), let it warm up for 10-15 minutes and it smoked heavy at first but thinned out. Once I got in it and began to drive it started smoking (still white/blue) really heavy again all the way up until it just hit the warm tick mark. I traded my 7.3 in for this truck and understand the diesel "puff" at start up but this seems a little excessive. Like I said, even in the summer with temps above 90 degrees I would still get a truck sized cloud of smoke at startup, but it would only happen on a cold engine, never on a warm one. Thanks ahead of time for any suggestions.
