Oh I see!  The head bolts screw into a thread cast into the block!  Only way round it is to retap & use a larger thread really.  I don't think a helicoil would be strong enough!

Have been onto a local engineering company that do engine rebuilds and repairs, they recon they can pop a helicoil to repair the thread for £40 which doesnt sound bad.

I have to say that im a little unsure that it would be strong enough but they seem to think it will be fine.

Just to keep this thread upto date, i got the thread repaired, and all i can say is he did an awesome job on it. Dont think it was a helicoil that was used, looks like some sort of full thread insert, the heads gone back on today and they all torqued up fine, result! :smiley:
