Car Engine Making Tapping Noise
A tapping noise coming from your car engine can be a sign of a serious problem. It is important to have the noise diagnosed and repaired as soon as possible to prevent further damage to your engine.
Causes of Engine Tapping Noise
There are several possible causes of a tapping noise in a car engine. Some of the most common causes include:
- Valve lifter problems: The valve lifters are responsible for opening and closing the valves in the engine. If the valve lifters are worn or damaged, they can cause a tapping noise.
- Piston slap: Piston slap occurs when the piston is loose in the cylinder bore. This can cause a tapping noise that is most noticeable when the engine is cold.
- Connecting rod bearing problems: The connecting rod bearings are responsible for connecting the pistons to the crankshaft. If the connecting rod bearings are worn or damaged, they can cause a tapping noise.
- Spark plug problems: If the spark plugs are loose or damaged, they can cause a tapping noise.
- Exhaust manifold problems: If the exhaust manifold is cracked or damaged, it can cause a tapping noise.

Diagnosis of Engine Tapping Noise
Diagnosing an engine tapping noise can be difficult, as it can be caused by a variety of factors. However, a mechanic can use a stethoscope to listen to the engine and try to isolate the source of the noise. The mechanic may also perform a compression test to check the condition of the engine’s cylinders and pistons.
Repair of Engine Tapping Noise
The repair of an engine tapping noise will depend on the cause of the noise. However, some of the most common repairs include:
- Replacing the valve lifters
- Repairing the piston slap
- Replacing the connecting rod bearings
- Tightening or replacing the spark plugs
- Replacing the exhaust manifold
Prevention of Engine Tapping Noise
There are several things you can do to help prevent an engine tapping noise, including:
