The leaking coolant catches my attention. That's indicative of a blown head gasket. Did the car overheat at any time prior to the problem? Do you have coolant in your oil? Check your dipstick. Is coolant coming out of your exaust pipe? If so it most likely is a blown head gasket. You might have coolant in your hydrolic lifters that causes the ticking sound.
