You MIGHT be able to get an oversized one take the plug with sleeve into an autoparts store and see if they have a kit /bigger then the one currently the kit includes a tap kit and a threading tool to install the coil
Thanks I will look around and see. Others have mentioned something called a time sert. Looks to be like $300 for the kit... wow. But they say it does a better repair especially when a helicoil repair has failed. thanks again for the response.
