friend you are lucky this is no big deal at all...

first there are a number of ways to repair this....

none of which require removing the head... and i think i could do it with even the exhaust manifold still on....

here are a few ways that come to mind...

there is a right way and a wrong way i will list both...


rightway
1. go to autozone and buy a tap set for about 9 dollars. use the correct tap and just screw it in and it will recut the threads... now buy your self a new stud or bolt and screw that in and your finished.

2. if this does not work go up to the next size tap and buy the next size bolt.

3. if this does not work then you can buy whats called a hellicoil that will insert into the whole....

4. a shorter bolt may do the trick...



wrong way
1. let engine cool and put JB weld in the whole and screw it in.
