Default Frustrating toilet flush pipe leak - any tips and tricks?

Warning: amateur plumber at work...

I installed a bathroom suite five years ago, and until a month ago it worked
perfectly. Then I got a leak from the toilet soil pipe outlet. It turned out
to be a split connector, which I have replaced.

Unfortunately, having now taken the toilet bowl out a couple of times to fix
the original problem, I now have a leak from the connector to the bottom of
the cistern - where the flush pipe exits.

I have tried packing with petroleum jelly; I have tried winding PTFE tape
around the outside of the thread; I have replaced the O ring. I still have a
miniscule leak - about 3-4 drops in an hour after flushing. I fear that the
thread on the outlet might be crossed as a result of overtightening.

I seem to have a few options - please could you comment on these?

1. ignore the leak - it is only a few drips per flush. It probably doesn't
matter. (I'm not too happy with this one myself)

2. pack around the *outside* of the connector with plumber's mait. (Might
work, doesn't seem too sensible)

3. put silicone gel into the connector, and hope that it seals off the leak.
(Might be a problem to remove later)

4. replace the flushing mechanism in the cistern, and install a new
connector to replace the possibly crossed thread. (relatively expensive, but
might have to be done finally to correct the problem).

I should mention that I am likely to be selling the house in a year or so
(market permitting), so I could live with a minor bodge - if it works!

Thanks for any suggestions,

John.
