back in the 1970's I ran a W115 220D/8 and my friend ran a W123 240D.
Both always dripped tiny quantities of oil from the sump nuts. I think
this is due to the fact that metric thread is relatively coarse, and
the frequent removal of the nut brought about by regular oil changes
introduces wear or play. We used to change the oil at 3000 miles for
long life - it worked. If ever we had the engine out, for example for
a clutch change, we would close up the original sump nut with weld,
and install a UNC or UNF fine-thread nut. That always cured the drip
problem, and I have done it since on many cars. The 'odd' nut in the
sump doesn't matter because it is not likely to get mixed up with
fasteners from anywhere else.
