2 Answers
Introduction to the causes of increasingly loud engine noise in Changan Oushang: 1. Aging engine mounts; 2. Aging engine supports; 3. Severe carbon buildup in the engine; 4. Faulty engine cylinders; 5. Poor lubrication; 6. Excessive wear between pistons and cylinder walls; 7. Engine overheating, cooling system failure; 8. Exhaust system blockage, vacuum tube leakage or breakage; 9. Loose belts. Solutions for loud engine noise: 1. Replace engine oil and oil filter, clean the engine; 2. Inspect the working condition of pistons and cylinders; 3. Check the condition of the cooling system; 4. Examine the tightness of the belts; 5. Add engine oil to improve lubrication.
I think there are quite a few reasons why the engine noise becomes louder, mainly because the car has been used for a long time and some parts naturally age. For example, the belt may become loose or worn out, making a squeaking sound when rotating; the engine oil may be of poor quality or insufficient, leading to increased friction due to inadequate lubrication; carbon deposits accumulate in the engine, causing uneven combustion and louder noise. Also, a loose exhaust pipe joint can produce a hissing sound due to air leakage. All these can be prevented with regular maintenance, like changing the oil every 5,000 kilometers and checking the belt tension, which can effectively reduce noise. I remember my car was like this last year, and it became much quieter after maintenance. Don't wait until the noise gets louder to deal with it, or it will be more expensive to repair. Regular checks can save a lot of trouble, safety first.
