Going through antifreeze....

I have a 92 diamante with about 155k miles on the engine and about 285k total miles. For some reason it goes through antifreeze, but I dont think its the head gasket. It for some reason keeps pushing the antifreeze into the reserve tank and overflowing the tank and thats where i lose my antifreeze. I have almost killed my car several times to over heating. Lucky it has it a sensor that shuts the car off automatically otherwise it would be dead. Any ideas.... plus i have the lifter tapping to any cures for that? As they are really expensive to fix. lol

there is a dye out there that you can put into your radiator tank. What you do is mix that dye in and then run your car and once you 've ran it for however long you think it needs to be ran you can take it somewhere dark and with a special pair of goggles check for that dye.
