OK dieselheads, can we all calibrate our smoke colours please?

Got lots of useful info in my last question about this, but there seem to be some differences of opinion. Here's my understanding so far. Are there any mistakes? Could you correct? Thanks!

BLACK SMOKE is soot, from incomplete combustion. The fuel isn't burning properly. Caused by:
- lack of air (clean the filter)
- cold (run it longer and on load)
- bad firing (clean the injectors, check timing, check the glows)
- deposits from the last time you ran it off load (don't do that again)

BLUE SMOKE is the lube oil burning.
Caused by:
- piston rings passing
- gasket blown

WHITE SMOKE is completely unburnt fuel flying out of the exhaust in a cloud.
Caused by: ?


So what happens if your gasket blows and you get water in the cylinders? What colour of smoke is that?

Answers:
head gasket or coolant leaking into combustion chamber.

your are burning water ie steam
white smoke is steam :(
mostly good. white is usually the fuel pump dying. the gasket blown is usually orange and red.triangles behind your vehicle 'cause it just quit!
white smoke is caused by burning coolant.
White smoke
