Should there be a hole in the transmission housing here?

Hello all,
My Bongo is a 2.5 diesel year 2000.
If you have a look at this Lush projects diagram (where would we be without them) you'll see a small rubber plug on the underside of the transmission housing. Part 16-145 towards the top right of the diagram.

The original rubber plug had a gap of about 10mm x 20mm where it fitted into the metal transmission casing. You could look up through this gap and see the shiny gear ring flywheel (part 11-502). It was as if the plug had been made too short. Other than this, the plug fitted perfectly.
I ordered a new plug (took a couple of weeks to arrive from Japan - cost was £3.50) and this was exactly the same as the old one.
It appears odd there should be a gap here through which water / muck could enter.
I could just make a plug that fitted out of the two I have but should I?....Should there be a gap here?
Cheers

Cheers Teenmal.
Most holes in such components, often used for venting pressure and the like, go through quite torturous routes.
This is direct access into the case and appears a little odd. A small (ok, very small) inhabitant of a hedgerow could get in there. I'll remember it's there for when I get the underside cleaned and re-waxoiled
