I have a head to exhaust manifold stud (rear upper) that is stripped and leaking badly. A previous repair had been made on it at a local Fiat shop and they used a "Time-Sert". (http://www.timesert.com/) Now that repair has failed and the Time-sert just rotates freely.
So my question is: Has anyone had experience using Time-serts? Can the old one be removed somehow and a larger one installed?
Would rather not buy a new head since I spent $1500 getting this one overhauled.

Re: Exhaust manifold stud stripped/leaking
the problem is that now the hole is much larger than originally. Another time sert still won't have enough material to grab unless you go with a larger size. You may have to get the hole welded and redrilled, but it's hard to say without seeing the head

I can check with Time-Sert about installing the next larger size and try to find a stud w/ 2 different diameter threads. Sounds like a treasure hunt...
