No argument that the use and location of the cowl-vent drain-hose is a poor design. However, if it is "correctly" routed, it does not seem that a lot of water would find easy entry into the clutch (bell) housing. However, isn't there an opening on the front lower face of that side of the clutch housing that might allow "correctly" drained water to enter?" If there is a hole on that side of the clutch housing, what is it for (seems like a bad design)?
Perhaps 4OTF is referring to the faulty situations wherein the hose is broken or missing (or, maybe the hose is pointed to the center rear of the engine and water drains over the rear top of the clutch housing).
I always thought the hole "6 inches south . . " was designed to direct into a single pan (placed by the owner on her/his garage floor) the mixture of engine and transmission (and differential) lubricants that seemed to leak into the clutch housing from old, or poorly installed, or poorly designed rear seals, oil pan gaskets, valve and side cover gaskets, transmission seals and gaskets, and torque tube seal. Also, any water that "correctly" drains (during a heavy rain) on that side of the engine but finds its way into the clutch housing. Isn't that what you all thought?
The caking of grease and dirt than accumulates on the bottom and side covers of the cluch housing appears to be a common, if not a normal characteristic of these wonderful engines.
This drain hole lets the engine (clutch housing) gently weep (it would be nice to say "weep in one place", but we know better).
