White smoke on cold start

Did a search and found that this could possibly be fairly common/normal for a 7.3 with some miles. Not a new problem just thought i would ask what the smoke is caused from and if its doing any damage.

I have 175k miles with no chip and full exhaust/intake. Glow plugs are original. Have new ones but have not got around to replacing them. Its 30 degrees on average where i live. I cycle my gp's twice for a minute or two each cycle. Starts up everytime with a single cloud of white smoke. It does not keep smoking while running. Just one cloud after startup. When running it runs perfect with no smoke of any kind hot or cold.

My geuss has been the white smoke is some fuel thats not being burned because my gp's are worn out. Is this correct or do i have some sort of problem.

That's no problem at all. White smoke is perfectly normal. The first burn when it's cold outside is what's causing it. Cold cumbustion chamber temps burning cold fuel. Your GP's are maybe a little old but they're probably working fine if it's firing up easily in colder temps. I would say don't sweat it.

Thanks. I wont. I know on a gas motor if you have a cloud of white smoke on cold start its blown HG or possible head warpage letting coolant in the comb. chamber.

Im happy it starts in this weather. My last 7.3 was an 89 IDI and it was a 50/50 chance in any freezing weather.

Yeah, with a gasser you might worry if it didn't clear up. And an IDI in cold weather is a frustrating thing sometimes. My brother-in-law's fires up like a champ. My father-in-law's, not so much. Then it threw a rod. Haha.

Damn, yeah my idi had some blowby and bunch of other crap going on with it. Had one of those banks sidewinder kits on it. Terrible. Turn the boost up a hair and egt's go through the roof. Glad i sold mine before a rod went in it.
