Broken engine support: symptoms and remedies

The engine mounts are rubber blocks mounted on steel brackets bolted in place to support the engine and reduce the amount of motor vibration and the noise that is felt in the passenger compartment. Usually there are three or four of them.

If the gum is consumed or cracked, or if the steel brackets break, the most common symptoms are more vibration of the engine or movement under the throttle and more noise. The engine may also move a few inches or more when the supports are broken. But here’s more in detail the symptoms that you can easily notice and that will allow you to act accordingly.

1 – Motor vibration

The first symptom to note is excessive vibration of the engine. Since the engine mounts are designed to keep the engine securely secured, if the engine runs badly the engine will bounce. Sometimes, there may be a sound emitted by the engine in vibration, however, the most common symptom is a vibration of the felt or seat on the passenger side.

2 – Misalignment

The protection of an engine not only fixes an engine but aligns it, which means that the engine height is secured to be equal on all sides. If the engine mounts are secured, the engine will lower and tilt to the side. Even in this case, there may be noise emitted by the engine instead of the right sound. Check the engine to see if it is inclined. If so, your media are not doing their job.

3 – Damage to the engine

The third symptom is an extreme case. If the engine mounts completely disengage from the engine, and are not just loose or broken, a motor can jump from side to side bouncing. This presents a safety risk if you are driving the vehicle at high speeds: the engine can move and bounce with such violence that various parts will fly away.

4 – Broken belts and flexible hoses

In addition to breakage of engine parts, bad supports can lead to damaged belts and tubes. Again, the various engine fan belts and radiator hoses will be damaged only during high speed driving.

5 – Excessive noise

The previous symptoms include parts that are not working, parts of the strap engine and tubes. However, the most common symptom is just the excess noise. This noise in general means something is wrong. It can therefore mean one of the previous symptoms, or something completely new but no matter what the problem is, it means something is wrong and needs to bring your vehicle to repair immediately.

Many engine mounts can be replaced for a digit and at a reasonable time, and some do-it-yourself mechanics boast having replaced them for less than 100 euros. Be aware, however, that lifting any engine is a serious thing, and if you do not know what you are doing, you could seriously damage the engine and your car.

The engine is generally lifted with a hoist to take over the weight that first fell on the broken supports before they could be replaced. Manufacturers often leave little room for work, extending the time needed to replace the media and put it back together. So in general, repairs can cost up to 200 euros.

Operation may take up to three or four hours if the engine is difficult to lift out of the bonnet and the other parts have to be removed or loosened to allow the operation. In cases where cooling and draining parts are involved, new gaskets or hoses may be required. Therefore, always ask for a quotation for the replacement of the engine mounts.
