Engine shock cooling on the ground

[Mike Kimball]

Everyone knows that shock cooling can be a problem with some aircraft
engines during rapid descents but how about shock cooling the engine on the
ground by shutting it down when it's very, very cold outside? More than one
person has expressed concern over my short exhaust due to the short path to
the heads for cold air to meet hot heads and cause a crack. I would think
that if it's a problem for my aluminum Chevy with aluminum heads it would
also be a problem for aircraft engines that typically have pretty short
exhaust. I'm interested in opinions, and possible solutions if it is a
problem. My plane is finally ready to fly and, of course, my luck timed
that with the onset of winter in Fairbanks, Alaska.
