Water tank goes empty after 50 to 60 miles driving?

options
check ALL water hoses for cracks if o k
check the radiator core if o k
check radiator expansion tank cap, seal maybe gone
the cylinder head could have cracked or head gasket could have blown
cheapest option replace the pressure cap and see if it cures it if not
be prepared to lay out some serious money and down time without the car
