Engine Mount Inspection

CAUTIONBroken or deteriorated mounts can cause misalignment and destruction of certain drive train components. When a single mount breaks, the remaining mounts are subjected to abnormally high stresses.
CAUTIONWhen raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal, or the crankshaft pulley. Due to the small clearance between the oil pan and the oil pump screen, jacking against the oil pan may cause the pan to be bent against the pump screen. This will result in a damaged oil pickup unit.
  1. Measure the engine movement at the engine mount in order to check for damage to the rubber portions of the mount. Apply the park brake. Start the engine. Firmly apply and hold the primary brakes. Have an assistant stand to the side of the vehicle in order to observe for engine movement. Slightly load the engine shifting from drive to reverse a few times. If the engine moves more than 24 mm (0.945 in) from the at rest position, in either direction, check for loose engine mount or engine mount bracket attachments.
  2. If the engine mount and engine mount bracket bolt torque is at specifications, check the condition of the engine mount.
  3. Replace the engine mount if any of the following conditions exist: Heat check cracks cover the rubber cushion surface. The rubber cushion is separated from the metal plate of the mount. There is a split through the rubber cushion.
  1. Remove the front suspension crossmember. Refer to «Front Suspension Crossmember Replacement (With Z06 or ZR1)»(/chevrolet/corvette/c6-2004-2014/remont/frames-subframes-crossmembers/#frame-and-underbody) or «Front Suspension Crossmember Replacement (Without Z06)»(/chevrolet/corvette/c6-2004-2014/remont/frames-subframes-crossmembers/#frame-and-underbody) .
