Q: Car making clicking sound at startup

asked by on

When I turn the car on, it makes a clicking noise.

Hello. It is important to consider whether the noise is heard when you are trying to start your vehicle, or when the motor actually starts. If it is before the motor starts, then the issue is most likely a low battery. If it is after the engine starts, the noise is probably related to the hydraulic automatic valve adjusters having low oil pressure before the engine warms up. Please ensure that you have the proper oil level in the car, and that it has fresh engine oil. If the noise goes away after warm-up, you may want to put in an oil additive designed to help valve lifter noise, and try it for a while to see if the noise is less during start up. These hydraulic valve adjusters must have clean oil in them, and it may take several oil changes to insure they have good oiling. If the noise continues, then you should consider taking your car to a qualified technician for further diagnosis and repair of your clicking noise concern.
