If my dads diesal is puffing white smoke every so often, is that an indication of anything? I noticed it while we were moving (somewhere in South Dakota). It would puff once and then it could be hours before it would do it again. But it did it on the hills in Tennessee more often.Does this mean it is burning coolant? My fatherinlaw says that it could be normal, but I don't quite believe him. How does one go about testing the compression on a diesal? Or for a bad head gasket? It had problems pulling another truck, and this has all got me thinking. I am not quite as worried about it now that we are home, and the truck won't really be going far, but it needs to be corrected eventually.

It could be coolant, but a good guess would be air in the fuel system. A bad injector o-ring, bad high pressure pump, bad seal on the filter or other parts of the fuel sytems. I know that if you drain the fuel/water seperator on my diesel and the bowl fills with air I get lot's of whiote smoke for the first few minutes to all the air is purged. How is the coolant level? If you are not needed to add to it on a regular basis I would bet on air being sucked in somewhere. Later, David Cole

White smoke generally means the diesel is "lean". Bad injector, air getting in fuel lines, bad fuel, or water in fuel. Alot of times, if the fuel is bad or low quality, like off road fuel, you'll get alot of white smoke at start up and the engine might clear up after a few minutes.

I put coolant in it in North Dakota (beginning of trip) and haven't needed any more since. But it puffed that white smoke.How would I go about fixing a lean fuel mixture on a diesal? BTW it is an 89 with a 7.3 (I believe)
