My wife had some coolant problems today and it turned out to be that
coolant was leaking (spurting) out past the o ring that is around the
temperature (level?) sensor that gets screwed into the coolant reservoir.
So... I'm hoping that it is just a simple O-ring issue and not anything to
do with combustion gases. If combustion gases were leaking past the rings
and into the cooling system wouldn't that lead to a higher pressure in the
system and cause the coolant reservoir cap to open (assuming that it is
working correctly) and cause a coolant overflow from the overflow tank
rather than the reservoir tank??
     Incidentally... still looking for a source for the big resistor up
behind the drivers side headlight that controls the speed of the radiator
fan.
