=== Causes of broken motor mounts === Motor mounts live in an environment of heat, oil and fuel leakage, and constant vibration and stress. They reside in close to 1000+ degrees of heat from the exhaust manifolds or headers and are subjected to deterioration by oil and fuel leakage from the valve cover gaskets and fuel lines. Most OEM motor mounts are made from compound rubber and steel frames. Many motor mounts will spend a couple hundred thousand miles and decades of use before ending their life. The final result of their life will be 'shear', whereby the upper and lower units of the mount will be torn in two, usually caused by engine torque finally overcoming the mount's ability to remain bonded together.
