I've never worked on one of those before (personal preference) but I assume that if you're lifting the whole end of the car instead of just the engine, you haven't got enough of the mounts free. For example, if you have 3 mounts, and you unbolt one, you've still got two mounts that are not going to let the engine move very much. You're trying to take enough of them out that the engine will pivot at the remaining ones, get it? You're not trying to raise the engine by using a subframe that is still very rigidly attached to the car, are you?

If you're trying to replace a tensioner for the timing belt, most cars don't need to have any special fender modifications or any need to remove the engine, if that helps at all. TH=here should be a fairly easy way to do what you need to do.
