How to Solve the Problem of Loud Engine Noise?

[OLayla]

There are several solutions to the problem of loud engine noise: 1. Aging or loosening of engine mounts: Engine mounts are rubber blocks between the engine and the frame. Solution: Tighten or replace the engine mounts. 2. Improper use of engine oil: If the viscosity of the engine oil does not match the engine, it can easily cause carbon buildup, leading to increased engine noise. Solution: Use the engine oil grade specified in the vehicle manual and avoid mixing different brands of engine oil. 3. Engine misfire: An engine misfire means one or more cylinders are not functioning properly. Solution: Check the working condition of each ignition coil and cylinder spark plug.
