Default please help, my 97 civic d16y7 engine is loosing coolent somewhere?

OK, so as i am driving, 3-4 days later, i have to add coolant. THE FAN WON'T GO ON WHEN IT GETS LOW ON FLUID, AND WILL CLIMB TO 3/4 HOT. THIS IS WHEN I SLOWLY LOOSEN THE CAP TO BLEED THE AIR OUT SO I CAN ADD COOLANT, AND 4-5 DAYS LATTER I HAVE TO FILL AGAIN. NO LEAKS IN THE ENGINE BAY OR DROPS UNDER THE CAR, ALL HOSES LOOK GOOD, water pump looks ok, timing-belt is dry, WHEN I BLED THE RADIATOR OF AIR, LEAVING THE CAP ON LOOSE, I NOTICED THAT WHEN I REMOVED IT W/ THE CAR ON, I SAW BUBBLES AT THE TOP OF THE FILLER HOLE. from what i can tell, it is pushing it out of the reservoir. I PUT IT AT THE MAX LINE AND IT FILLS ALMOST FULL, is that a SIGN OF A blown head-gasket? THE OIL LOOKS LIKE NO WATER IS IN IT, IT WILL BURN DOWN A QU 3K MI LATER. No smoke from the tailpipe and i sniffed it and it smells fine, isn't the reservoir fluid suppose to go back into the radiator? THINGS I HAVE DONE: fresh antifreeze, new thermostat, new rad cap. radiator looks dry, no coolant on the floorboard.

the cooling system on our hondas is a close system. if the level is going down, you are either burning it or have a leak somewhere. how many miles are on your car?
