Since this only happens in the morning AND it isn't noticeable after that all you're doing is burning off the moisture that's collected during the evening; like dew on the grass in the morning. The same thing happens to cool metals at night. Makes sense too that it seems worse after the initial start, you haven't heated the pipes enough to burn everything off at first but you have got them warm enough to pull additional moisture out of the air. Then you start it again & all the original what's-left-over moisture plus all the new stuff you've collected burns off in one big poof!
BUT, if you notice white smoke while driving or after its warmed up then I'd be concerned & start to think about valve gaskets or cracked heads, etc.
Kurts is correct.
Just FYI :
Black smoke = fuel...running rich
bluish gray smoke on deceleration = oil...usually bad valve stem seals
bluish gray smoke on acceleration or idle = oil...many causes...worn rings / cylinders, cracked heads / block are the most prevalent.
pure white smoke = coolant...usually a cracked head, block, or intake manifold on some cars.
Back in my auto mechanic days one of the big pranks was to put a cup of coolant down the tailpipe of a car someone just spent a lot of time working on. (this works even better if someone just rebuilt an engine and you can pour the coolant right down the exhaust manifold) Once they start it up the thick white cloud starts rolling out. You'd be amazed at how much smoke a cup of coolant will make!
As for your problem Darice57, my bet would be on condensation.
