Blew out spark plug sleeve
 

Hi Everyone,

My car started sounding like a John Deer tractor as I pulled into the garage the other day.

I opened the hood and there was a spark plug with a small threaded sleeve around it laying on top of the valve cover.

Is there a previous post that anyone knows about that talks about replacing this - do I have to pull the head, special tools... any advice ?

thanks

It sounds like someone stripped the head and installed a helicoil thread repair kit

Can a repair be made "after" a helicoil repair has failed without pulling the head?

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

I've heard it done with head on

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.
