1-3-2-4 Posted May 22, 2013 Share Posted May 22, 2013 So awhile back I had a bolt that went in and kind of mangled the threads to the driver side head, so I have a exhaust leak in that area and it's a little annoying how would I go about fixing it?

El Presidente Posted May 22, 2013 Share Posted May 22, 2013 Thread inserts are what your looking for. The most common brand is called Heli-coil and any autoparts place will have them, but you're gonna need the "kit". It has the install tool, coils and instructions, but I think you need to buy the drill bit separately. If you feel comfortable tapping a hole by yourself go for it, otherwise have someone else give you hand. It sucks if you get it in there a little sideways. Your gonna need to drop the y-pipe too, so don't forget to unplug the O2 sensor, or you may need a new one of those. Josh Quote Link to comment Share on other sites More sharing options...
davebugs Posted May 22, 2013 Share Posted May 22, 2013 NAPA has an excellent selection and most weird sizes. Timesert/timecert's are newer and seem better but I haven't used them yet. Infact I'm trying to remember what heli-coils I do have. Because the kit, and drill bit can get kinda expensive for a one tim euse. I baby the flex joint behind the Y-pipe anytime I drop a Subaru exhaust manifold. Quote Link to comment Share on other sites More sharing options...

1-3-2-4 Posted May 23, 2013 Author Share Posted May 23, 2013 Thanks a little pricy for the heli-coils but I guess it's good enough for now.. I plan on switching to a EJ22 next year for turbo purposes. Quote Link to comment Share on other sites More sharing options...
