Hmmm, thinking about it a bit, any shock cooling should be worse on
the front two cylinders rain or shine.

An analyse of failure rate by cylinder position would be interesting.


Yes, my thought exactly. I wonder if anyone keeps such data? I know
when I owned my Skylane, we never had any unusual issues with the front
two cylinders. This data, if available, would certainly provide some
indication if shock cooling is real or imagined.

My O-320 had 2 cracked cylinders (both on the left side) at the same
time. This was the year after the exhaust stud hold cracked on
the right front cylinder. Shock cooling? More likely due to the fact
that these were cermichromed cylinders with an unknown number
of hours on them before they cracked at 600hours SMOH.
