ehall you need two pair of vise grip needle nose on the tappered sides of one pair of the vise grips grove the outside with an angle grinder so when it is clamped on the not makes a flat surface. Get the second pair and then clamp the first pair to secure the vise grips from slipping creating a lock then twist and wala!! never failed me got a pair of vise grips i have used just for this a handful of times. Hope I got to you in time there. I may have a pic on my other pc to display what I mean.

Get thyself to Ace Hardware and buy a set of COBALT bits. Those babies will cut throught that old crumbly bolt stub like butter... (really, they will).

Let me add.... you may want to just buy one bit, as the are very expensive!
I drilled right through the old stud in the water pump in no time ... It was so clean I just chased the threads, and put in a new stud ...

+1 on the cobalt bits. I probably have hundreds of cheap, black and decker, you name it bits, that are useless except on aluminum and PVC....
Not cheap, but once you use good bits, you'll be able to tell instantly when you accidentally chuck a black and decker bit up.

I know you don't have a welder, but see if you can bribe someone with beer to come help you. MM951 had a similar situation with a broken lower shock mount bolt. After weeks of fu*king with it, he brought it over to me, and in a few minutes it was out.
It's almost like magic, I'm telling ya!

To center the bit on the stud use a drill bushing. set the head on and put the drill bushing in the hole. This will allow the drill to center on the stud. If you order from McMaster they ship next day for about $5. Also look at their drills, they have carbide tiped bits that will drill through grade 12.9 bolts (the really hard ones).

All told you should have about $20 into tools to drill it.

Marines can break anything. I have some friends at Davis Monthan AFB here in Tucson. Some Marines flew in an F18 of the first block and rumor is the Air Force boys were so scared of the condition of it they decommissioned it on the spot and sent it to the bone yard.

I still believe leaving the broken stud in is better than breaking that tab off of the block. Like I said before, 64K+ miles on my engine with that stud broken (bought the block with it broken - didn't know until it arrived!) after spending too much time trying to remove it and bringing it to various machine shops etc. The bolt is 15 ft lbs, if the other bolt is still good I don't think it will be a real issue.

This is the ONLY fluid leak I have on my NA currently, and I want it GONE!
BTW Mike, did you get my PM RE your M3?
