the expansion tank doesn't "boil", it's gas from a leaking head gasket
getting into the coolant and bubbling through to the only possible exit,
the expansion tank. coolant in the exhaust is only a late stage symptom.

sorry about the bad news, but you need to get this fixed right away
before damage to the head or block occurs. confirm with a hydrocarbon
chemical test of coolant fluid if you wish to be sure. but head gasket
is a 99.999% certainty.

if price is a factor, suggest you look into the cost of repair vs.
replacement of the motor. many head gasket repairs are not done well
and engines tend not to last well after surgery. it'll cost you $450 -
$600 for a low mileage used motor from japan - and labor to swap is less
than all the work necessary to do the gasket.
