It might be a battery or alternator problem.
If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn’t have enough juice to stay powered. So instead, it rapidly turns on and off and produces a clicking noise!
Why is my car making a clicking noise while idling?
Typically, most cases of ticking sound in the engine while idling are often due to an unadjusted valve train. Each time your engine spins twice around, the valves have to open and close once. In a single cam engine, the pushrods are actuated by the cam, and they open the valves via a lever known as the rocker arm.
Does low oil cause engine knocking?
Low Engine Oil
A low oil level can cause engine knocking. If you get lucky, the noise may subside when you refill the engine with oil. In most cases, however, once the oil level gets low enough to create knocking, damage to internal engine components has already taken place.
