forgot to say push the block back and forward with your hand make sure its cold first if it moves the mounts have had it but to test them properly you need another person to sit in the car with it running and lift the clutch up as far as you can without stalling or moving (dont stand infront of the car my dad made that mistake) the block will move ideally you want little movement if the front mount has gone the engine will move about 3/4inchs up and youll see the mount compress about 2 inchs the other way it should be solid.
