What would cause antifreeze in my engine oil. Is it the intake manifold gasket?

From my experience antifreeze in your oil or vice versa would mean that you have a blown head gasket. If your intake gasket was leaking the only thing leaking would be antifreeze and it would be on top of the engine around the valve covers or the intake manifold. Hope this helps
