Can anyone recommend the best way to get the old bit out and suggest
how to repair/re-thread so I can use it again?

Stud Extractor

+1


Is that some sort of goo providing an additional seal? Is it hard or
soft? Either way, I think I would attack it gently with a wood-working
chisel to try to chip or prise as much away from the interface as
possible, as it will be contributing to the removal torque. Ideally I'd
try to make the thread interface visible, and soak it with some sort of
penetrating oil. The very last thing you want to do is apply so much
torque that you damage the boss or the threads. Remember that a stud
extractor tends to expand the male part, making it tighter.

I have used a punch or something similar to wind out a bolt. It may
loosen the thread sufficiently for a stud extractor to work.
