Car Engine Tapping Noise
What is a Tapping Noise?
A tapping noise in your car’s engine is a repetitive, metallic sound that increases in frequency and volume as the engine speed increases.
Causes of a Tapping Noise
There are several potential causes of a tapping noise in your car’s engine:
1. Valve Lifters
Valve lifters are small components that help to open and close the valves in your engine. When they are worn or damaged, they can produce a tapping noise.
2. Piston Rings
Piston rings are metal bands that seal the combustion chamber in your engine. When they are worn or damaged, they can allow gases to escape, which can create a tapping noise.
3. Connecting Rods
Connecting rods link the pistons to the crankshaft in your engine. When they are bent or damaged, they can produce a tapping noise.
4. Main Bearings
Main bearings support the crankshaft in your engine. When they are worn or damaged, they can create a tapping noise.
5. Fuel Injectors
Fuel injectors spray fuel into the combustion chamber in your engine. When they are clogged or damaged, they can create a tapping noise.

Some common fixes for a tapping noise include:
