I've had my turbo/waste gate and exhaust manifold out for an overhaul, when putting everything back with new bolts/ gaskets etc, one of the stud holes connecting the turbo to the manifold has lost it thread.

'Helicoil' is your solution, it's the original thread insert system that is now used as a generic term. Bit like most people hoover with a Dyson...
Do a Google search and you'll get lots of info and choices for helicoil kits.
Alternatively drill & tap for the next size up...

Thought what was written was quite clear and unambiguous Steve,

Yes but the question is has the thread been stripped from the stud or the hole, as it is an exhaust it most likely have seized and stripped the thread.
If it's just the stud then the hole could probably be salvaged by carefully running a tap/taps in the hole, but this isn't an easy job as the tap could snap giving you another problem

Helicoil would be too weak for this application, you'd be better off with something like this

Defo the thread gone on the manifold. As I've got new studs going in. And I can see excess thread bits in the hole and the stud in perfect condition. Now to look for some helicoil s and figure out sizes. Cheers lads.
