[TR] TR3 New Rear Main Seal Leaking

[David Lylis]

Bill,
Apparently this is a very familiar theme.  I have the same issue, although
not as severe as you seem to have.  I have discussed this with others who
have made this conversion and have the same or similar complaints.
I think it is from some of Uncle Jack's stuff that Tony posted online, but
the length of the spring that fits into the seal factors into the cure.  I
seem to recall that the spring needs to be shortened, therefore tightened,
to 8" in overall length before putting into the seal.  I am working from
memory here so do not act on this information until you verify yourself.
I am going to get to this in a couple of months so I am not paying strict
attention to the details now.
