REFLECTOR: Engine Lubrication

Interestng idea.  If I've done my rough calculations correctly, a pint of water would cool 8 qts of oil by 85 F.

Interesting on the mineral oil comment.

So, I have a crazy idea regarding engine cooling.

If there is an emergency need for engine cooling, like near or beyond 
redline, would the introduction of water as a fine mist into the engine 
case be a way to cool the engine without damage to the engine?

One would think that the water would flash to vapor and be carried out 
the case ventilation tube in very short order.
