Do fuel injectors make a ticking noise?
Fuel injectors are small electrical valves that make clicking and ticking sounds when quickly opening and closing at idle. Ticking of the injectors is normal and you can drive without any worry.
Why does my car make a ticking noise when I idle?
A ticking noise could be caused by any number of reasons, such as a low amount of oil and loose components. You may hear the ticking noise while the vehicle is idle, accelerating or even after you have received an oil change.
What to do when your car engine is ticking?
Make a visual inspection when the engine is off and cool. Replace if any of them is cracked. Wiggle the plug after removing the spark plug wire to see if it moves. If yes, then you have to tighten the plug. Sometimes, the torquing of the plug is not correct. In that case, you have to re-install it by following the owner’s manual.

What makes a rattling noise at idle speed?
The noise only happens at idle speed, as soon as you touch the accelerator it goes away completely. All temps, oil pressure, power, smoke, etc stayed normal…the noise was the only thing new or out of the ordinary.
Why does my engine make a ticking noise?
A loose or damaged engine fan can also be the reason for engine ticking or tapping noise. A visual inspection is enough to find out the problem. Check the bolts and clips to see if they are loose. Also, you can tell if the fan blades or shroud on the radiator are damaged just by looking at them.
Why does my car make a clicking noise when I idle?
The first noise you described sounds like valve lifter noise. You will hear this sound if the engine is low on oil. Check the oil level and add if necessary. The lifter noise is not heard at higher RPMs because the oil pressure is higher as the engine speed gets higher. If you have high mileage, you could benefit from the next higher viscosity oil.

Why is my engine ticking at idle and acceleration?
An exhaust manifold leak is the cause of engine ticking at idle and acceleration. It happens when exhaust gases leak at high pressure from a leak in the gasket or a rupture in the manifold. This is not a serious problem, and you can still drive. But, fix it as soon as possible because excessive leaking of exhaust gases won’t be good for the engine.
