White smoke at start up

I have a 2001 F350 7.3 diesel and this year during cold weather start up it produces white smoke until warm. It starts on the first time but i am just wondering about the smoke. Is this something i should worry about now?

Is it excessive? A little bit isnt enough to worry about.

Quick causes/most common causes of white smoke- Glow plugs/relay going out, injector issues, coolant leak.

My guess would be your glow plugs are getting weak, since you said white smoke goes away after its warm. But older diesels produce alittle white smoke usually in cold weather start up's.

Sorry for bringing up a dead post, but the OP of this thread has the same issue I have been having. I have an 01 7.3 Powerstroke, roughly 200K on the clock, and in temperatures around 50 degrees and below on initial start up for the day I get a nice amount of smoke coming from my exhaust I would describe as grey/white/blue mixed, and smells bad (unburnt fuel?). I have an Edge Evolution CTS tuner, and have noticed that once the oil temp reaches 65 degrees the smoke is gone. I have a GPR LED mod, so I can tell that my relay is at least working (not sure whether its sending full amperage or not?) the truck starts pretty easily but runs a little rough until about 3 1/2 minutes of idling. I have no coolant loss, and lose a little bit of oil which I would blame on a dipstick O-Ring leak. Truck doesn't run poorly, or miss once it is warm. It also doesn't matter which tune I am running on the Evo.

Any opinions or thoughts?
