I attempted to fix my exhaust leak and made it worse with a bolt extractor kit. The extractor broke off in the block (top right hole). I tried to drill it out over the past two days but only made the hole bigger around the bottom of the extractor. It seems to be welded to the top of the hole.
The bottom stud was previously stripped and a bigger bolt was used instead of a stud. If you can't tell from the pic, the bottom right hole was stripped again while removing the bolt. The bolt was never torqued down good enough to prevent leakage, carbon deposits are all over that area.
Three things I'm considering:
1. Trying a diamond bur to drill out the top and using a time-sert on both?
2. If 1 fails, use time-sert on the bottom only.
3. Have the car towed to a machine shop.
Open to suggestions. Thanks.
