Hi David,
Just had a look at mine. There is 3-4 mm clearance on mine.
As suggested do check the mounting, mine did fail and sagged. Try rocking the engine and see if you get a knocking as the exhaust taps on the bolt. New engine mounts have a strengthener on them so it is a known problem. The weld that goes is the one where the bracket is welded to the flange at the engine end.
Also check that you have the correct bolt and washer combination on the single engine mount bolt and the two mount to chassis bolts as any miss match here will be critical.
If all is ok with the mount, bolts and washers just pack washers under the engine mount to rubber bobbin bolt.
