Does the clicking sound seem to get louder the longer you let the car sit without starting it?
I'd once parked mine for a time, waiting to change a leaky water water pump, timing belts, oil seals, accessory belts, etc and occasionally started it in order to move it only short distances. Soon I was more concerned about a loud clicking sound than I was about the leaky water pump.
Add about half a quart of good synthetic oil, idle the engine for about five minutes and if it quiets down, switch to all synthetic at your next scheduled oil/filter change.
A few thousand miles of smooth, quiet driving later and after replacing the water pump and belts, one of my injectors failed.
