My radiator has been leaking, and ive tried patching it with some solutions purchased from Lorco, Canadian Tire, etc.

Nothing has stopped it, and it has overheated a couple times. Each time the temp. gauge starts to rise I try to find a gas station to fill up the radiator. Unfortunately, the last time it started to over-heat, I was on the highway with no gas stations near. When I finally arrived, I filled it up, but when I try firing it up, it didnt work.

The overflow tank is filled with a white liquid that has bits of oil, which leads me to believe its a blown gasket.

Im not a mechanic, so I dont know what the price will be to fix this, and I am hoping someone can help me with a price quote for the fixing of a head gasket.
