What Happens If a Motor Mount Is Broken
A motor mount does more than simply hold a motor in place. A motor mount utilizes a rubber bushing to hold a cars engine, which helps to dampen vibration and movement that can cause damage to the engine and surrounding components.
Noise and Vibration
A broken motor mount will cause a significant increase in noise and vibration. As the motor moves within the broken mount, the engine often strikes the mount, creating a loud thump. The normal vibration of the motor that is dampened by the mount will often also be transferred to the entire vehicle, causing a noticeable shake.
Engine Component Damage
As the motor moves, damage may also occur to the flexible hoses and wiring that run to the motor. While these parts are designed for flexibility, the sudden and longer movements of a motor that is not properly secured can pull wires and hoses loose as well as weaken them. A broken motor mount may also cause exhaust leaks.
Motor Mount Damage
When a motor mount is broken, the motor is allowed to move more than intended. This causes additional stress to the other motor mounts, which will quickly wear and may break under the added strain.
