Should have sent this in text file format earlier.

Are you sure it's your rear main seal??  I too have a 3 main B motor in my
MGA.  I
have a leak.  But the leak is transmission oil - and this is common.  So
common
that there is a hole drilled in the bottom of the bellhousing to let the oil
get
out - should be a cotter pin in the hole to help direct oil out.  Also, there
really is no rear main seal in a 3 main MGB motor (or MGA motor).  It's a
tight
fitting backplate with a scroll that should push any oil back to the
pan......and
there's a groove cut in the backplate to direct any leakage from there out in
front
of the flywheel, on ont the flywheel/clutch.

Designed oil leaks - aren't they great!! It's not leaking, it's just marking
it's
territory.  When it stops marking it's territory - then you know you have a
problem.
