T Listers:
I'm in process of rebuilding my MGTD engine and I've progressed as far as
replacing the rear main oil seal.
I'm following the method in Horst Schach's book of refitting the crank
over and over using machinist's blue to check the clearance of the upper
seal.
One curiosity. When I disassembled it, the upper seal had a rather large
piece of felt kind of wedged underneath it, so it would also wipe the
crank. Obviously, this was meant to reduce leakage out the rear of the
engine. Anyone seen this setup before? It must not work, or everyone
would be doing it, right? From my books it appears that there is no
seal material used beyond the metal fittings. Is this correct?
I've heard enough controversy about Moss' rear main oil seal conversion
to avoid it, particularly for $200. However, has anyone had any
experience with the front seal conversion? It is much less expensive at
about $10 and may be worth a try.
