Unless I'm mistaken i think its safe to assume this is whats making the noise... unless the tensioners really do loose this much tension without the engine running

Here is a video of how loose it is:
You just need to do the new timing chain, tensioners, guide rail replacement as so many of X5s go through with the V8 engine. Not a terribly difficult job but tedious. You'll need the cam locking tool kit to make the repair.
