Wife's '01 Impala has a leaky head gasket. Under oil cap is kinda milky and radiator has some rainbow colors in the coolant from oil.
If we don't fix it, about how long can the motor run with a leaking head gasket berfore it dies? Will changing the oil more frequently help it last longer?
Hoping to get another car in a couple years, so that is why we don't want to put another $1000 in this one.
Thanks
