The Simplest Method to Deal with Car Valve Noise
2 Answers
Here are the simplest methods to deal with car valve noise: 1. Valve leakage noise: Treatment method: Remove the cylinder head, grind the valve, check the spring tension of the valve, and readjust the valve clearance. 2. Valve knocking noise: Treatment method: Readjust the valve clearance. If the lock nut on the adjustment screw is loose, it should be securely locked, and severely worn parts should be replaced. 3. Valve seat noise, seat ring detachment or rough surface of the valve seat ring: This could be due to unqualified machining precision, improper selection of the interference fit leading to looseness, improper material selection causing excessive deformation under heat, or substandard valve seat installation process. Treatment method: Reinstall the valve seat according to the assembly process requirements, ensuring the upper surface is flush with the body plane, and any protruding parts should be smoothed down.
What is the simplest way to deal with car valve noise? I've encountered this issue several times while driving. The most common causes are excessive valve clearance or insufficient lubrication, resulting in a clicking sound from the engine. The simplest solution is to drive straight to a professional repair shop and have a technician measure and adjust the clearance with a feeler gauge. Spending a little money can solve the problem quickly and effortlessly. For example, last time my car had severe noise, I immediately went to the garage, and it was quiet after a ten-minute adjustment. For prevention, regular engine maintenance is essential; check the oil level to ensure sufficient lubrication, as low oil can affect valve lubrication. Don't underestimate valve noise—prolonged neglect may wear engine components and even increase fuel consumption. Safety first; addressing it early benefits both your car and your wallet.
