Why does my car make a clicking noise while idling?
The most common cause of engine ticking is a noisy valve train. Your valves have to open and close once for every 2 times your engine spins around. If there is excessive play in these components you can usually hear them “tick” as they shift around while your engine is running.

Where does the ticking sound come from in an engine?
Piston slap is a ticking sound coming from the lower parts of the engine (the pistons moving in the cylinders). If you have piston slap, you may need to replace the entire bottom half of the engine to get rid of the sound, as pistons typically aren’t the only worn component — typically, cylinders are worn as well.
Why is my engine ticking when the oil level is low?
If the oil level is low, the ticking might be because upper engine components like the camshaft and valvetrain are starving for oil—in which case you need to add oil right away to head off serious damage and determine why you’re low on oil to start with (leak, oil consumption, etc.).
Why does the timing chain make a ticking noise?
The timing chain can also make a ticking or tapping noise if oil pressure is an issue. Start by checking your oil level. Always do this with the car on a level surface. Pull out the oil dipstick, wipe it off, reinsert it and then pull it again.
