Water not coolant. The crank case contains air which contains good ole fashion H2O. It now has even more air with the additional blow by and open breathers. Small amounts of condensation can occur in the crank case especially after the car sits. Ever send oil in for analysis? They tell you to make sure the engine comes up to temp to make sure you burn this water off to make sure it does not impact the analysis.
Air does not equal H20 my friend.. water is H20.
Sure, a minute amount of condensation could come out of the air... but not in the amount of fumes that are shown in the video here especially......
