Tried the search function but no broken crank bolts.
Basically took my car (08 350z, Base, MT) to Mike's Z in Whitter,CA for a clutch/slave cyl/ master cyl/front brake job. When they removed the old South Bend Clutch plate, they saw that two of the bolt heads of the eight bolts that hold the flywheel to the crankshaft, were gone!
Upon further inspection and removal of the flywheel, they saw that the two bolts were not actually 'missing', but were instead sheared off inside the crank snout, almost flush with the crank.
I've had a few machinists look at photos, but have had quite a few people flake on me as far as coming to Mike's to do machine out/extract the bolts. Mike's Z Shop says they have no way of removing them without destroying the crank/crank threads, they are recommending a low-mileage engine () but I refuse to go that route for 2 bolts. Mike's Z says I can bring an outside machinist to remove the bolts, use their lifts and tools if necessary.
Any suggestions, advice, some quicker way then bringing a machinist to repair are appreciated, but anyone who can come do it, just message me.
Thanks!

^Right. Start small and work your way up to where you're about a millimeter away from touching the threads. Make sure you start at dead center though. Then, depending on how much you bored it out, you may be able to stick a 3/8in. internal pipe wrench in there to get the rest out. You can pick them up at Lowe's or Home Depot for like $15. If not just use a picking tool made of soft metal such as brass or aluminum. https://www.google.com/search?q=inte...w=1920&bih=974
I'd suggest trying to soak those threads in WD40 in advance. Then, slowly use a hardened bit in the center to start a small groove. Once it's deep enough, use a bolt extractor and say a prayer. If you can get a purchase with the extractor tip, try to slowly back that bolt out.
Sheared them all on my car, flywheel had been installed for 115k miles, came out still attached to the trans. Drilled it with a 1/16 drill bit, moved yup to I believe a 1/8th and finally a #2 easy out.

What I have in bold just now clicked.. If they removed your flywheel and snapped your bolts in the process, then they should be responsible for extracting them. End of story. Don't let them pull the wool over your eyes by saying that they were already like that. They look as if they were twisted off with an impact.
Good luck getting a shop to cover broken parts. I don't know of a single shop good and bad that replaces broken parts during an install unless total fck up.
Most the time they just bill you and tell you it was going to need replacing anyways.
Why would a shop be responsible for bolts that break when REMOVED?!
Why wouldn't they be?! If I'm doing a job and I break a bolt head off, I take care of it. It's called integrity. I'm not going to loose that much money, and that individual most likely will keep coming back. That's how trust is earned. And we all know how fuking hard it is to find a TRUSTworthy shop nowadays..

Some shops will honor stuff like that and some shops won't, and the ones that do usually have more customers. ..It's like taking your car in for a tune-up and they break one of your spark plugs in half trying to get it out. they don't just give it back to you like that and say "better luck next time". No, they fuking take care of it.
Not around here. Usually the busier shops are the ones who are faster to charge you. I'm not saying they would leave it in and say better luck. But they usually come along or "well one of your plugs snapped, you're going to have to buy a new plug". Then explain how it was already fracked or seized or some story like they couldn't do anything to save it.
Or like the bolts I'm sure most would just say "your boots were seized and snapped off, we can take them out with a tool but we will have to charge you labor".
Notice how each is worded like it's the parts or cars fault not theirs haha
I've worked, and been to a lot of shops in CA. I don't know of a single one that wouldn't hook the customer for at minimum extra labor for this "now more complex job".

Right. Maybe for a couple extra bucks, but I wouldn't pan it off onto someone else and say there's nothing I can do for you, here's your car. And oh btw, you can use my shop space and equipment to do the job too, but you're probably going to have to bring in a MACHINIST(lol) to do the job any competent mechanic could've done on his lunch break.
