This will need removed and another insert installed properly. The insert should be flush or countersunk to the work piece being repaired.
It's entirely possible you could repair it with a BIG-SERT, but you need to be absolutely sure you get it straight, like suggested above. If you do not, then you're in for even more hassle.I will remove it and give it another shot, if the original threads that are tapped into the aluminum head are angled and not straight, will I need to use a big sert? Or could I run the drill bit provided with the kit in there again and retap the threads again straight?
