HI - If you are still not sure, then snap nor was I, so I jacked up the engine via the gear box and slipped out the mounting which only took about half an hour and checked it out - yep it was buggered (am I allowed to say that) okay so I had to slip it back in til I get another but at least theres no more trying to figure out. It is more than likely that you would be able to tell if the mount is shot just by jacking the engine up and looking at the mount as you do so
cheers
Steve
