[Mg-mmm] One more time... chasing oil leak around vertical drive on P type

After two attempts to cure.. replacing the double lip seals... the car
still "atomizes" the small leaks onto the flexible coupling and then
delivers a fine oil mist over the engine compartment.
I did the vertical drive alignment (thank you Bill D.) *again*, new seals*again
* (after having IBT re- mic to ensure proper sizing) ... new gaskets and
seals and a small dollp of RTV.
If anything, it's worse. Used to leak when engine was running.... now
overnight, top of dynamo and coupling is showing oil just sitting there.
Dynamo is not charging (not fully checked out yet) but fear oil is leaking
into the windings....
Now going into unknown territory. Looking for things to check beyond the
obvious
1. Should there be a paper gasket between the bottom of the front cam
support assembly and the receiving casting that is part of the head? It is
directly above the vertical drive assembly and oil seems to always be on
bottom of the drive bearing housing. Might just be thrown there.... or
bottom seal just leaks!
2. Does the orientation of the flat on the metering pin (like a clock face)
have anything to do with regulating the amount of flow of oil to the top
end? Could not find any mention... nor feel anything as I rotated thru 360
degrees. Pin meets dimensions in Blower.
Any other things I can try?
Thanks
Don B.
