A bit of trivia: When glycol antifreeze became standard, some engines had to be
redesigned a bit to minimize the chance that coolant would leak into the
crankcase.
For example, the holes in the block for the head studs needed to be blind: they
could no longer pass through the deck into the crankcase.
This is because when glycol antifreeze gets into the oil, it can turn into a
gummy
goo. If pure water leaked into the crankcase, it would simply evaporate.
