 Subject: Odd Smoke Problem
IP: Logged
Message:
Hey all. I was merging onto the interstate the other night, usual procedure (wind it to 4k in 3rd, gets me to my 75mph cruise speed nice & quick), but something happened this time that I've never experienced: from 3-4k, my Dak started blowing what was either a cloud of fine dust or not-very-dense smoke from the tailpipe. It doesn't use any coolant or oil, so I doubt it's burning those fluids. Did it just blow out some carbon, or should I be worried? Any input would be much appreciated; thanks in advance, guys.

And the fact it never happened before does not rule out a leak like a head gasket letting coolant into cylender or oil from a possible bad seal on a valve just going bad just to name a couple off the top of my head. Keep your eyes open to everything untill you nail it down.All problems have a starting point.
So many problems .... So little time

Sounds to me like you stirred up the accumulated carbon and moisture in the exhaust. Mine will do it to when I putter around town for a day or two then hit the bypass and wind it out. At night with someones lights on it, it looks like a huge cloud, it's not. Try it in the daylight.

Thanks to all for your replies. In response to the first 4 replies, it happened at night, so the darkness plus the cloud being of such low density prevented me from being able to tell if it even had color, but I appreciate the suggestion. DrPepper & daddio, you described exactly what I experienced - it was at night, and in the headlight shine of the cars around me, it looked like this massive dust cloud. I took your advice, & lugged the truck around town a few more days, then wound it out during the day - couldn't see any smoke, just like you said. OBIO3 & bigdave, thanks for the tips, especially re: the brown smoke signalling cat failiure; I'd never heard about that before. BTW, haven't experienced any smoke of any color before or since the incident I initially described. Also, still no coolant or oil use (only got 53k mi on it). Thanks again guys!

Has it done it again? If not, then it is not something to worry about. see if you can make it do it again if not dont worry.

From time to time I see huge puffs of smoke come from all sorts of vehicles, at a constant speed, as opposed to hard acceleration. I immagine it must be the exhaust caughing up its version of a hairball, since it only seems to happen once.
