[6pack] Engine cracks from freezing water

[Robert McBride]

Not a surprise as what some of you are calling freeze plugs are really core
plugs and are there to get the casting sand out of the motor when they are
poured.... they are not there to protect the motor from freezing...  Now they
will pop out if the block freezes but they are not there to stop the block
from cracking...  Bob  M

  btw, the freeze plugs were intact...go figure,  I was told that during a
long
  deep freeze (Saratoga New York), the engine will freeze and thaw at
different
  rates, somehow this predisposes the block to failures not protected by
freeze
  plugs
