I just recently noticed the other day pulling out of my neighborhood a barrel of white smoke coming out of my exhaust. It eventually got less noticeable to eventually none once I was around operating temps.

This morning fired it up, puff of grey smoke. Pulled out of neighborhood, white smoke not as bad to eventually none. I stuffed it a couple times around operating temps and smoke seemed a bit lighter than usual (grey) exhaust does not have a haze either, when it stops it stops.

267k miles, intake, exhaust no tune, completely stock. Water does not seem to be down any further than usual, and it is not discolored by any means. Oil dipstick does not seem to be any higher than usual and I believe smells normal.

Truck starts up quicker than my brand new f150, no misfires, no loss of power, idles perfect.

Any ideas?

Pull your air filter pipe/boot off of your turbo inlet and see if it is all black and oily inside of the turbo. If so you have a busted seal inside your turbo allowing oil from the feed line to get into the inlet side of the turbo and you are burning it out of the tailpipe in the form of the smoke that you see. Reason why it clears up after warmup is because the oil left in the turbo/line after you turn the truck off pools up in the turbo housing. When you start it again, it smokes until you burn that pooled up oil out. After you burn that oil out it won't pool up or smoke again until you turn off the truck and let it sit again. Fix is to rebuild turbo or get a new one.
