Blown head gasket question?

[Ice Cold]

In my experiences whenever the head gasket blew the oil and water always mixed. My friend has a 95 5.0 with 100k plus miles and the dealer is saying it has a blown head gasket, but he says the oil and water isn't mixing. Is this possible? He says whenever he turns on the heater he smells antifreeze. Sounds like the heater core to me, but the dealer told him that it's a blown head gasket.

I thought the same thing when my heater core went out. It smelled like anti-freeze and I wasn't noticing any white smoke or anything. I'd see if there is a leak around the tube that comes out of the heater core into the engine bay 1st and then possibly deal with the head gasket if it is indeed the issue.
