The leak you are describing as from coming from the bell housing is most likely the valley pan gasket that is leaking. When it leaks (and it will on ALL M62 engines built prior to 2003), the coolant runs through weep holes in the back of the engine, down through the bell housing area and drips off the bottom of the bell. Pretty sure there is nothing in the bell housing that can leak coolant.

Take the engine cover off and look at the back of the engine on the top. If you see a pool of blue/green goo, that's the valley pan leaking. If you pay for this repair it's a few hundred in parts and about $1000 or more in labor.

Here is some DIY info:
