I just bought a turbo manifold from someone over the forum and the top stud in the picture is brokenoff and the bottom one is missing altogther. My question is can this be salvaged? Other then those problems it is perfect. Thanks guys.

Sure. Why not?



Extract the broken one and replace the missing one.

how do I extract the broken one, its flush with the manifold? I guess a a local hardware store has a stud for the missing one?

We had a stud get seized and snap when we were putting on my new exhaust. We had to take it to a place that was more experienced with that sort of fix and they used blowtorches to heat the hell out of it then break it out. Didn't cost us a dime.

mazda sells the studs, nf01-13-708a, they arent cheap though

I'd honestly just buy another one, and I'm even a really handy dude...I mean what do they go for on ebay? $30. You can try an easy out and a blow torch but those studs are in there pretty good...it may actually strip the easy out. Most likely it would work though. That or just drill that sucker all the way out, which could literally take hours...then you'd most likely need to retap the manifold...which I don't even 100% know is possible since its super tough cast iron. I've cut some of this material to do the non seq conversions...let me tell you it isn't soft stuff. Good luck

Don't chuck it. Don't let it get the better of you.



This is simple stuff with the unit on a bench. Try fixing a broken-flush rotor housing exhaust stud with the engine installed.



Soak it in PB Blaster and start with a sharp left-handed bit. If it isn't out by the time you've got a hole for your extractor (i.e. easyout) try the extractor. If all this fails then drill it out completely and re-tap.

I'd take it to a machine shop or even the dealership to see if they can help you out. I once snapped the studs from the throttle body and took it to a guy i know that works in the shop(and thats from the frequant visits i had for buying parts) and he gladly replaced the studs for me at no charge! so see if they can help.

couldnt you just weld and old bolt you dont want to the stud and just find a socket that fits the old bolt and twist it?
