Does a damaged engine mount affect the engine?
2 Answers
Yes, a damaged engine mount affects the engine. Once the engine mount is damaged, significant resonance will occur between the engine and the vehicle frame, causing body vibrations and unusual noises. The main material of engine mounts is rubber, and under normal circumstances, they generally do not get damaged. However, if you frequently drive at high speeds, go over speed bumps, or often drive on poor road conditions, you should be cautious. There is no specific replacement interval for engine mounts, as their normal service life can exceed six years. If you notice signs of cracking or aging in the engine mounts, they should be replaced promptly. Typically, there are three engine mounts fixed to the vehicle frame. If one is damaged and not replaced in time, it disrupts the balance and can accelerate the wear and tear of the other two.
I've worked in an auto repair shop for over a decade and seen many customers with failed engine mounts. This isn't a minor issue - engine mounts are crucial for cushioning the engine's attachment to the frame. When they fail, the engine starts shaking violently, making the whole cabin vibrate while driving, with the steering wheel shaking like a massage device. Prolonged vibration can loosen other engine fasteners and cause surrounding oil/water hoses to leak from being stretched. Worst case scenario is engine misalignment - the engine can drop and hit the chassis, potentially damaging the transmission or driveshaft. Last year, one customer ignored it until two engine bolts vibrated loose and snapped, resulting in repairs that cost more than replacing three sets of engine mounts.
