This is a local customers car I am currently repairing. I went at it from the outside to show what lies behind the engine mount in some cases. Form inside the bay the mount " appeard " to be fine. This video will show otherwise. The other spot to check is the lower part of the mount with the curved recess in it. That section tends to rot through and can be seen from inside the engine bay, prior top doing any real work. included is a poic of the mount form the front side once after I knocked all the scale out form the other side. Prior to knocking the scale out, the upper section of the mount looked fine, the lower did not though.Enjoy
