2K 7.3 Starts fine but smokes first 1/4 mile
I recently purchased a 2000 F250 SD, 7.3l engine, and 65k miles. It starts great, lopes just a little bit when it is cold (<30 degrees-F), but otherwise seems to be fine. The minor rough idle goes away rather quickly (2-3 minutes).
The issue I have is the amount of white smoke this thing puts out when it is cold outside. I have talked to a lot of the "local experts" (the stealership wrench turners, local diesel shops, and others that own a 7.3 of the same vintage) and they all say that the smoke is nothing to worry about. One of the guys even smelled the smoke and told me that he was certain that it was just unburned diesel coming from a cold engine.
On my next days off I plan to check the "health" of the GPs and will look at the GPR with testing that I have gotten from some of you on this site. Assuming that the GP stuff checks out okay (and it is starting well), do any of you have any ideas as to what can be done to reduce this smoke? When I leave a parking lot, you can see where I started and the path I took to get out to the road. It's getting a bit embarassing.
By the way, after about 1/4 mile (after she has warmed up a bit), everything clears up and I get no smoke. Nothing when I mash down on the throttle, nothing when I sit at a light and then take off, nothing when she is just sitting there idling.
I yield to your past experiences and appreciate any insight you might have.
