On what basis did you make this statement? I would cite a source to back
this statement up or to say it really diplomatically.

I just looked up my Bentley and located a picture (not drawing) of the
rear side of a split block. The hole I was talking about has connection
to the chamber where the two crankshaft gears (to drive camshaft and
distributor shaft) are located. It then connects to the chamber below
the gears where the large diameter gear on the rear end of the camshaft
is located. The center of this large gear has a slot for the oil pump
driving gear shaft to reach and be driven by the camshaft.

The oil I poured in through the hole should end up in this camshaft gear
chamber from which the oil pump driving gear is driven. Although there is
a removable oil pump housing right there next to the large camshaft gear
but because the oil pump driving gear shaft is in this chamber. Perhaps
the oil I poured in reached the pump housing from this chamber through
some openings that are not shown on the picture.

I dug out a Vanagon parts manual, full of parts drawings, given to me
from JWalker more than 10 years ago. And I found similar drawings that
show how the hole connects to the chamber right behind the oil pump.
Thanks to the hospitality of JWalker I still look up this parts manual,
almost 2 inches thick, from time to time for information.

This could be still a complete BS so use your own discretion. But I don't
think it was coincidental for what I experienced. I can agree even the
Bentley has the picture that shows it and even the Vanagon Parts manual
has drawings about it I will still say that it can be just a fantasy of
mine.

Hope this is diplomatic enough this time.

David
