@scooper321 great job in testing and to your conclusion, I would now get a compression test. It does look like is may be a head gasket. As @PlayDate mentioned, the antifreeze would settle to the bottom of the pan, when the oil gets hot any water would start to "boil" off and that would create the milkey foam on the top of the oil. As the dip stick is removed some of the foam will attach itself to the stick. The green residue of the antifreeze would stay at the bottom and get mixed in with the oil.
