Bryanj:
You cant replace half a case anyway, has to be a pair. I would think a helicoil would do the job, the torque is not super high
juitz:
I'll try a helicoil tomorrow - called a local shop and they use time-serts. Any preference one over the other?
Laverdaroo:
I prefer the time-serts over the helicoil. Although quite dear, they're never going to move of snap etc. I had three done on the 400 cases as they were completely shot. They just feel more substantial than helicoils.

Only issue is that the time-sert need a seating surface. As the case has a counterbore section, not sure I'll have enough material to drill and allow the time-sert to seat at the required depth.
K2-K6:
A properly installed Helicoil will easily handle the torque requirements for this application. It'll not be a compromise to use this, plenty of lubricant to drill and cut the thread slowly and you'll get good tolerance on final installation.
Straight through hole such as spark plug etc you'd certainly give more consideration to timesert type repair.
