Left Engine Mount, Corteco - F22 M235xi, F30 335xi, F32 435xi
OEM replacement motor mount eliminates vibrations and restores smoothness. Direct replacement for BMW part #22116856403
Stock motor mounts are filled with a vibration-dampening fluid giving them a hydraulic like absorbency. Mounts go bad when the fluid leaks or evaporates from the engine mount, leaving a rubber block that is far too flexible and "squishy" to do a proper job of supporting the engine. Once the engine mount fails, it causes engine shaking, vibration, as well as unwanted driveline twisting. This twisting action will harm the rest of the drivetrain bushings (like transmission and differential mounts) as well as the metal motor mount arms that hold these in place. In some cases the engine can twist far enough to cause contact with other components (such as a fan into a radiator or a belt into a hose).
