Car Engine Making Clicking Noise

If you’re hearing a clicking noise coming from your car’s engine, it’s important to take it seriously and get it checked out by a mechanic as soon as possible. This noise could be caused by a number of different problems, some of which could be serious if not addressed promptly.

Causes of Engine Clicking Noise

Valve Train Issues

The valve train is a complex system of components that control the opening and closing of the valves in the engine. If any of these components are worn or damaged, it can cause a clicking noise.

Lifter Problems

Lifters are small, cylindrical components that sit between the camshaft and the valves. They help to reduce friction and wear between these two components. If a lifter fails, it can cause a clicking noise.

Fuel Injector Problems

Fuel injectors are responsible for delivering fuel to the engine’s cylinders. If a fuel injector is clogged or damaged, it can cause a clicking noise.

Piston Slap

Piston slap is a condition that occurs when the pistons in the engine are loose and able to move around excessively. This can cause a clicking noise.

Connecting Rod Bearing Problems

Connecting rod bearings are bearings that connect the connecting rods to the crankshaft. If a connecting rod bearing fails, it can cause a clicking noise.
