1G Exhaust mani studs broke

[ARCHangel8788]

So my manifold had a crack in it. So i replaced it. In the process most of the studs broke off. I have 4 or 5 hold it on now. Best ways to get these out easier the better and if all else fails ideas on what a machine shop might charge to get them out. It's a 91 gst 6 bolt.

If you can't weld you will likely need professional help.

If you got lucky and they broke with exposed threads then you can try to put two nuts on the remaining stud, tighten the nuts together, and use the inboard one to loosen the stud. If there isn't enough threads for that method then use vice grips or weld a nut to the exposed stud. If the broken stud is tucked in the head then you can attempt to drill into the stud and use an ez-out (keep in mind that if you break a drill bit or ez-out in the stud your day just got way worse). Or just pull the head and take it to a machine shop.

Well i don't weld but my buddy does. There are a few that are tucked in there. But these are the oem studs from 91. Never thought of welding it thanks for that. Machine shop would cost a lot probably huh?

depends on the shop, I've had shops drill and remove a broken stud for $20. I've paid $150 for a shop to use an EDM to get rid of a stud I broke a drill bit in.

Try a local shop and see if they will cut you a break, if not then find a welder who will do the same, sorry to hear about the misfortune...

Get the manifold off.. and use vicegrips+heat? Pictures would be helpful.

Have you actually tried this and had it work? Youtube is one thing, but real world experience is something different...

Get a drill punch. Center it and punch it. Use a drill to try and extract the bolt.

I concur. If you drill, punch them first. I've had good luck with extractors. Just don't force it. Break the extractor and there is no easy was to get it out. I've done at least a dozen.

Left handed drill bit kits from Fastenal are what managed to get my snapped studs out. I had a friend that extracts broken bolts out for a living so he made it look easy.

Best pic i have right now. I will get a better one. As you can see most of the studs are gone

Your going to get all kinds of exhaust leaks. Best way if u dont want to remove the head is a center punch and extraction bolt set.

My favorite way is using a mig a washer and a nut , just did one on a dsm head today took more time to set up the welder.

Yeah it has exhaust leaks I'll try your guys different ways and see what works. If all else fails machine shop.
