How to Solve Loud Car Engine Noise?

[ORylee]

Solutions for loud car engine noise: 1. Poor fuel quality causing loud engine noise: When low-quality fuel is used, the combustion inside the engine deteriorates, leading to strong vibrations and noise during operation. The solution is to promptly switch to high-quality fuel. 2. Loose plastic parts in the engine compartment causing noise: If inspection confirms that the noise is coming from plastic components, tightening them can resolve the issue. 3. Loose engine mounts causing loud engine noise: Engines are typically supported and fixed by engine mounts, which can age and loosen over time, leading to noise during operation. Inspecting and tightening the engine's mounting components can alleviate the noise. 4. Loud engine noise during cold starts: When a vehicle has been parked for an extended period, all the lubricating oil flows back to the oil pan, preventing the engine from receiving adequate lubrication. This is a normal phenomenon.
