Bell housing huh? Maybe could be a leak from the back of the top part of the engine (read: valve cover gaskets), then dripping down on top of the bell housing, then down towards the bottom of the bell housing. With the car cold, run your hands around the back and sides of the engine, where the valve cover meets the block and see if it's wet with oil. Though if there's that much, you'd usually expect to see a little white smoke and smell it too. But you never know. GL!
