Machine shop can fix it, but the Head has to come off. You'll need to flush as much off the particles out off the combustion chamber and around bearings before re-assembled.

Edit: Keyserts would be a better option.

 

Here's some good reading on Heli-coils

y does the head have to come off to do it right??? thanks guys for your help

 

The difference between Heli-coils and Keenserts/Keyserts, is the ability to rotate an insert. Keyserts are designed with four KEY features to prevent this from happening and are preferred in Aerospace, Naval and any other application that requires a far superior insert. Specifically designed for Aluminum application and since the head has to come off, why settle for less.

 

anybody running a helicoil ??

because if you don't take it off you'll be getting a lot of metal shavings inside the cylinder. kinda bad for your engine
