Clicking means metal on metal and no oil in between. Check your oil, oil and filter changed?
Don't drive it if it gets worse - there is a glog somewhere - or it is too late already.
Detonation...Needs to be fixed immediately or will eventually destroy engine.
A clicking sound, when trying to start the engine, indicates a dead battery or poor (dirty) battery or starter relay connections.The clicking sound is the starter relay(soleniod) not getting enough power to hold it's contact points together.
That is lifter noise, they probably need adjusting
the clicking sound is the blinker. when you signal to turn with your blinker the light flashes and makes a clicking sound.

AnswerIs the clicking sound from the engine? Try to check the oil.If this is happening when you try to start the car, it is most likely a weak battery or a bad starter. Oil would not have anything to do with this problem
fan belt or lots of things but most likely fan belt
clicking sound but engine wont turn over. jump across terminals on starter if engine turns over solenoid is bad.
Valves tapping?
possibly the timing chain tenisoner. wear on the plastic casuses a clicking sound.
If it is done by one person the sound is clicking, if it is done by multiple people it is an annoying sea of clicking.
You would need to provide more information. Does the click happen with key on and engine not started? Does the clicking sound come from the engine compartment? Does the click abruptly stop in a specific amount of time? Does it matter if the engine is cold or will it also click after the engine has stopped for just a few minutes like you would find when shopping or refueling? Does wet weather make a difference?
