The reasons for the loud engine noise in the Boyue are: 1. Aging engine mounts; 2. Aging engine mounts; 3. Severe carbon buildup in the engine; 4. Faulty engine cylinders; 5. Poor lubrication; 6. Excessive wear of pistons and cylinder walls; 7. Engine overheating, cooling system failure; 8. Blocked exhaust system, vacuum tube leakage or breakage; 9. Loose belts. Taking the 2020 Boyue as an example, it belongs to the compact SUV category, with body dimensions of: length 4544mm, width 1831mm, height 1713mm, wheelbase of 2670mm, fuel tank capacity of 58 liters, and curb weight of 1610kg.
I've been driving for over a decade and have repaired many engines. The most common cause of excessive noise in the Boyue is loose or aged/hardened belts, which produce a rattling sound when rotating. Then there's the oil issue – not changing it for too long or having oil levels too low increases internal engine friction, resulting in a harsh noise. Additionally, loose engine mount screws or worn rubber pads can cause significant machine vibration and double the noise. Sometimes exhaust pipe leaks can produce a whooshing sound, especially when there's corrosion or looseness at the connection points. I recommend first checking the dipstick and belt condition yourself. If that doesn't solve it, take it to a professional shop for a technician's diagnosis – early intervention saves big expenses later. Regular vehicle maintenance, including periodic oil and belt changes, helps prevent problems proactively.
