From your description, and the year of the car, my experience with these cars is that you indeed have a head gasket problem. You wont see water in the oil with these. The best way to find out is to find a shop with a tester to check for hydrocarbons in the coolant. Or you can buy a tester from a parts store. It's a tool that uses a blue colored liquid in it and when the HC's are detected the fluid turns yellow. If that's the case you're looking at around 4k to repair.
