A blown head gasket is not something you can take lightly. If it's not blown, then you may have warped cylinder head, or something else in your block that's causing problems. I'm no mechanic but I'm sure other people on here are more informative than I.
Yeah I cant tell if that is oil or coolant. If it is coolant then yes I would say your head gasket is blown, however you may also drain your oil and see if there is water in your oil that may be another sign that your head gasket is blown.
