My car loses coolant and my oil gets milky. Is this a blown head gasket?

Hello, first, you can't prove anything until diagnostic testing is performed. Have you or anyone else performed a cooling system pressure test to see if the leak can be located? If you somehow determine it is an internal engine coolant leak, this is not a "do it yourself" project for the novice home mechanic. I appreciate financial binds, but consider losing your vehicle entirely. That's a bigger bind yet.
