Engines have noticeably changed in the past decade. Fewer cylinders, more power at lower RPM and more vibrations able to be detected at idle are just a few of the differences of today’s engines.
For many years, auto makers relied on solid rubber motor mounts to support the engine. The natural flexibility in rubber allows the mounts to absorb vibration. However, if the rubber is too compliant, the engine may experience excessive motion under load that could stress and crack exhaust pipes and connections.
