Hi Team,
just to add to the discussion on this with two service Magazines on the subject.
The body oil /water seal should be a slim rectangular or square section O Ring from memory and fits into a groove in the base and around the protruding body--some Parts Books show the said seal mounted down on this protruding body and this is incorrect in my experience.

Regards,
Eddie B.
