V50 Plug thread repair

Sadly took my plug out the other day and the helicoil type insert from a previous repair came with it. Can these be re reamed again or receive new insert or is there a further repair possible?Â

You can have a new helicoil insert fitted, but there a recon heads on the bay for £40 and you may well do better going that route

You can replace the inserts.
If they give up the ghost like this it’s usually through poor initial application.
having said that a pair of heads at £40 is a bargain :smiley:
Good luck
