thats really not even an option. if anything ill have to just drill it all out and create a new thread.
Drill bits and easy outs are extremely hard and cannot be removed by ordinary means. It takes a solid carbide bit and extreme care to remove a broken drill bit or broken easy out. Now it is tow time to the automotive machine shop and pain in the wallet..

Rotsa Ruck said the little Chinese man...also the stud is slightly sticking out of the block. couldnt i possibly just have a good welder weld a nut to the end of it and try that?

Easy outs and drill bits cannot be drilled with ordinary drill bits, it takes a carbide bit, which is extremely hard. It is also extremely brittle and very easy to break if you apply too much sideways force. if you break off the carbide bit trying to drill out the broken easy out, there isn't much left that you can do. Last time I checked, thermonuclear devices were not available for your needs...
You need to get the old broken bolt out before you can tap and HeliCoil the hole back to the original bolt size.
Let us know how that works out for you.
Also I got ARP water pump and timing cover bolts as well as anti seize

And use oil on the bit and bolt. It doesnt really matter what kind as long as you use something. Engine oil is fine.
You realize if he breaks off the carbide drill bit then the block is toast, or if he lets the drill bit walk it will oblong out the hole. A carbide drill bit is very brittle and you cannot use a lot of force on it. IMO he has a better shot at trying to drill a small adjacent hole in the bolt and then try to use another easy out in that hole or a reverse drill bit to tryand remove the bolt. Only other option I see is bring the car to a machine shop and hope they can fix it.

Easiest way is to get a half size smaller diameter drill and drill into what's in there. Normally the thin side wall of broken bolts will be thin enough to fall out into pieces. If any is left inside you could step up the drill bit size and pray PB blaster etc into it and soak it and maybe just blow it out. Then you could lube up another bolt and run it into it breaking up the pieces off the wall and clean the remaining parts of the thread. I'd try that before taking the timing cover off. Unless you just wanna get in there and replace the chain etc while you're there.
Well this thing turned a mole hill into a mountain.....
At this point based on what I've read id strongly suggest having an educated professional drill the bolt out they will have all the tools, knowledge and patience. Slow and steady wins the race here that bolt is not easy to get out now.a
