That mallet-tap 3/4 turn after the oil pan drain bolt is hand tightened is probably a good idea.

But, at least on my 2002 525i, the oil pan design seems to preclude the use of a box or crescent wrench (see pic below). Do you think they designed it that way on purpose?

The only wrench I could get in there was a socket wrench.
