i never had a hg mix my oil and coolant together
When the engine is powering it pressurized the rad with leaked exhaust gases (which forces the coolant out of the overflow). When its a really badly blown gasket the coolant can pump into the cylinders as well and creep past the rings. This results in bearing wear. Can kill the crank as well.
If it is a BHG, replace it properly and never worry about it. If it hasn't leaked too long, the head and block surfaces won't be corroded. If you wait too long, the whole ball game changes. If you can smell it in the exhaust (or get white smoke plumes) its getting into the combustion chamber.
