When you next have the outer cover off:
Remove the O ring, fit up the outer case to the inner, gently and progressively tap around the cover with rubber hammer to ensure it is seated, finger tighten central nut. Now see if you can slip a 0.001" feeler gauge in between the inner and outer, at as many points possible all the way around; it should not fit...
Not all O rings are the same, some are too hard (old) not all are the correct length.
Nor are the O rings always correctly or fully seated into the groove. I find that with a replaced O ring it is advise to gently Tap around the outer case with a rubber hammer to progressively seat the O ring so that it mates fully as the central nut is SLOWLY tightened.
If all else fails: a smear of RTV works every time!
