engine and gearbox mounts

[ryobi]

Can anybody tell me what engine and gearbox mounts do for your car. I have no idea.

[Kinks]

they hold the engine and gearbox in place so that they can push the car forward effectively. If you had no engine/gearbox mounts it would be easier for the engine to turn itself rather than turn the wheels and push the car, so when you put your foot down you'd get all kinds of angry noises under the bonnet as the engine turns and hits your chassis as it does so, your engine would run like shit because it has ripped out all its vacuum hoses, coolant lines would pull off and you'd spray coolant everywhere, it'd rip your exhaust open so you'd get some nice unmuffled engine noises and then it would probably die when you sever some major electrical cables and the alternator/battery are no longer connected to the injectors. Also when you rupture your fuel lines, it'll start a fire when the severed electrical leads touch a body part and make a spark.

So in other words, engine and gearbox mounts are good to have. Why, is something wrong with yours?

Upgraded mounts will be filled with polyurethane rather than rubber - rubber allows more movement and less NVH (noise vibration harshness) in the cabin. However urethane mounts hold the engine/gearbox rigid so that you can be more precise and effective with your driving inputs through the rear wheels.

Personally I wouldn't bother, engine mounts are one of the last things to do - if you want to - because their effect is minimal compared with other mods.
