Series 3 Water pump, snapped stud

Afternoon landyzoners!
Shirley here, again
Just removed the water pump and have managed to snap a stud
Any ideas on how to extract said stud?
Or am I better off taping out the hole to take a slightly shorter stud?

Thanks in advance for any help

Also, what do we think about this repair!!

Thats a drain hole. They block them off so you don’t know if the pump fails.

If you have access to a lathe you could cut the broken end of the removed part of the stud drills pilot hole through the centre and thread it back in the hole and use it as a pilot to centre the drill when you drill the broken off stud.
think the thread is BSF unsure of the size so I would drill just under size of the thread and then tap to the correct size this should break the damaged thread from the wall of the stud hole
