[So my question is... can the head gasket be blown, leaking oil into the coolant and making a loss of power, but not be leaking coolant into the oil or combustion chamber?engine oil
------------------------------------------------------------
no!
but if you have a automatic trans and the radiator has i internal trans fluid cooler, transmision oil can get in the coolant and coolant can get in the trans if this is the problem dont drive the car till you get a new radiator and have your trany flushed and filter replaced
