What we're discovering with the C5s is that the breather systems are
not foolproof. Once the breather hoses become brittle and break, or
the suction pump becomes clogged, the pressure inside the head goes
crazy. When the pressure increases, the gaskets are being forced out
of place and voila, you've got an oil leak.

If you end up with a sudden oil leak during cold weather... clogged
breather system, full of ice.
