Attention: TDR Forum Junkies A couple of weeks ago, when it was kind of cold here (25 degrees), I found myself at a stop light behind a new F-350 drw. I noticed that vapor (like what you'd expect to see from a recently-started gasser) was coming out of the tailpipe. I thought to myself, "Self, I guess there's one ford buyer who didn't feel like getting the diesel option on his new truck. I wonder why?" Now before everyone thinks that I've confused water vapor in the exhaust with cold-diesel white smoke, let me explain: The vapor was completely gone within about 3-4 feet of leaving the pipe. Even my truck has a little white smoke on a cold day when I first start up; that smoke doesn't disappear like the vapor does - it is visable until it dissipates in the breeze, etc.
Anyway, once we had travelled about 3 miles we turned onto a 4-lane, and I could pass him. Wasn't I surprised to find that new diesel emblem on his door!? By now the vapor exhaust was gone, but it had been there earlier when the engine was colder. Is this something peculiar to these engines or their emission controls? I have never seen "gasser vapor" in the exhaust of any diesel. Any ideas? Just curious.
