1996 Lexus LS 400 Coolant Leak

I have coolant dripping from a hose every now and then. I clean the spot up and a day or 2 later there is a small amount of coolant back on the ground. I was wondering since I do have a couple of hoses on top of the engine that is going to the air intake that need to be replaced since there are hole with electrical tape on them. Could that be the problem. I do hear a light clicking noise coming from the engine as well.
