Engine valve tappet noise can be an annoying problem for many car owners. The ticking or tapping sound coming from the engine can make your driving experience less enjoyable. However, there are several effective methods you can utilize to eliminate engine valve tappet noise and restore peace to your car. In this article, we will explore some of these methods.

1. Identify the Cause of the Noise

Before you can effectively eliminate the tappet noise, it is crucial to understand its root cause. Typically, this noise occurs due to a lack of lubrication or worn-out tappets. Take the time to visually inspect the tappets and surrounding components to check for any signs of wear or damage.

2. Change the Engine Oil

Old, dirty, or low-quality engine oil can contribute to tappet noise. Changing the engine oil and replacing it with a high-quality oil that meets the manufacturer’s specifications can significantly reduce tappet noise. Ensure you follow the recommended oil change interval for your vehicle and be sure to use the right type and viscosity of oil.

3. Add an Oil Additive

If changing the engine oil doesn’t fully resolve the tappet noise, you can try adding an oil additive specifically designed for quieting tappet noise to the new oil. These additives typically contain special detergents that help clean and lubricate the tappets, reducing noise in the process. Follow the instructions provided by the additive manufacturer for the best results.

4. Adjust the Valve Clearance

Incorrect valve clearance can cause tappet noise. If your car has adjustable valve clearance, refer to the manufacturer’s specifications and adjust the clearance according to the guidelines provided. This process may require some mechanical knowledge or the assistance of a professional mechanic.

5. Replace Worn Tappets

If the tappets are severely worn or damaged, replacing them might be necessary. Consult your vehicle’s service manual or seek advice from a trusted mechanic to determine the correct replacement tappets for your engine model. Be sure to follow the proper installation procedures to ensure effective elimination of the tappet noise.

6. Seek Professional Help

If you have tried the above methods and the tappet noise persists, it is advisable to seek the assistance of a qualified mechanic. They will have the expertise and specialized tools to diagnose and fix the issue effectively. Remember, engine noise can sometimes indicate more serious problems, so it’s better to have a professional evaluate your vehicle.

Final Thoughts

Engine valve tappet noise can be a frustrating issue, but it is not insurmountable. By following the methods outlined in this article, you can take steps to eliminate or significantly reduce tappet noise in your vehicle. Remember to diagnose the cause, change the engine oil, add an additive if necessary, adjust the valve clearance, replace worn tappets if needed, and seek professional help if the noise persists.
