Why not use a washer or aluminum plate screwed secured by 3 screws (drilled
& tap 3 small blind holes into the plate) the sealer & pressure on the
retainer on the outer side of the seal will make a secure & safe
professional repair to your problem.

Hi Buly,
 
I have a sort of unique situation that wouldn't apply to most anyone
else.  My MM plate (NOT the one supplied by Tracy) has a slight
problem.  The recess for the rear seal was machined a few thousands too
large.  The seal was not a press fit so I agonized over what I was
going to do with it (last year sometime) and finally decided to hold
the seal in place with Proseal.  I don't think there is a lot of
pressure there, and I don't think it would leak too fast if it did come
loose, but I won't know until it happens.  I might be surprised.   If it
were to leak, I would prefer to not be pumping engine oil overboard
risking the engine as well as the redrive.
 
As a side benefit, I suspect the redrive would run cooler if I weren't
pushing hot engine oil thru it.  That should be better for the
redrive.  If I were to do it, there would be an oil reservoir, pump, and
small oil cooler.
 
I might mention that I will have at least 15 hours of ground time on
the engine before even thinking of flying it.
