Question White Smoke ?

when i bought my 93- F350 -7.3 IDI it didn,t smoke at all ( has a rebuilt engine with 100,000 miles ) but lately i have noticed this white smoke when i start it cold, smokes for about a minute or so then it clears up, no smoke once it's warmed up. I have been adding 2 stroke outboard motor oil to the fuel lately & wonder if this could be what I;m seeing?

Every diesel I have ever owned smokes white when it is cold outside after I first start them. It is perfectly normal in cold weather, now if it keeps smoking white all day at idle I would wonder if there was a problem. Your trucks sound perfectly normal to me especially if it quits after it warms up, don't worry!!! They will smoke less if you plug them in at night.

Yeah its just unburnt fuel until you engine warms up a bit. If you tune up the truck it will smoke more then if it has stock tuning

No problem!! Diesels are pretty cool and the performance they can put out is pretty incredible. I have never owned a gas powered truck, so I don't really know anything but diesels. You can learn an incredible amount on this forum, I learn something every time I log on! Good luck, let me know if I can ever help you!

Beg to differ - if it's cold out it's not smoke, it's condensing water vapor. If it's white smoke in warm weather, you have a problem - that's coolant burning off, leaking head gasket, cracked liner, something like that......sorry

a diesel will blow white smoke from fuel on a cold morning , you are right it will have condensation also, but not as soon as engine starts only after heat start getting into exhaust
