White smoke - '67 MG Midget

#1

Sometimes I get white smoke. Happens most often when I accelerate from standing still, or RPMs are below 3000. Car is running at normal temperature 190-200 degrees. No signs of head gasket leaks or enging block cracks. Friend says it needs a carburator adjustment.

White smoke means water or moisture in the combustion chamber. It may be from a tiny leak now that is hard to find, but will get worse as you go.


#3

Coolant, i.e. water, escaping from an engine in the exhaust as steam will dissipate quickly and disappear while oil smoke will remain visible quite a while in calm air. The odor of oil and coolant are quite distinctly different, also. And a rich mixture will cause oil smoke but usually black smoke will be seen often before the resultant oil smoke.
