Advice needed: DIY gone bad

[Viper01]

Guys, I need your advice so I know what I'm in for:
I just purchased a performance muffler from another Pelicanite; I soaked the bolts on the studs from the turbo to the cat as I'll be removing the stock cat and muffler as one piece. After soaking for a couple of days in PB Blaster, all the bolts broke free no problem with just an open ended wrench. As I was loosening the upper rear bolt (not even a full turn yet) it started to tighten up......yup, I think the stud sheared off. I marked the end of the stud to be certain and it moves back and forth with the bolt. I don't want to go any further until I know how complicated this is going to get if I have to replace a stud and/or remove the turbo. Any suggestions?

I suggest posting this in the 930 forum.

But, FWIW, a broken stud is not the end of the world. Some heat and a stud puller will help you to remove what's left of the stud so you can install a new one. If you can't get the stud out, then it can be drilled out (very carefully), but this will require the turbo to be removed from the car.

I am not an expert but that happened to me also. In my case I was taking the turbo off anyway. I then took the hot housing off the turbo and took it to a machine shop and they extracted the stud.

If you are luckey, after you get the cat & fuller out there will still be some shaft left to try to get a grip on. Otherwise I think you may be able to drill it and use a stud extractor. With all the heat that think went trough may or may not work also.

If not, take the turbo off and do as I did.

If you do remove the turbo make sure it get primed with oil before you runn it up.

Good luck.

Thanks for your replies guys! I'm gonna post this in the 930 forum as suggested.
Moderators, please remove this thread if you feel it's necessary.

Until then, the more info the merrier........

Can you see enough thread to start a nut on it? You may be able to plug weld the nut to the stud. May not be feasible in position...

While off topic, I feel the need to chime in...
I for one, believe your question to be of technical nature, regardless to the type of the car you drive. Just because its a turbo does not mean the question by nature is "turbo" specific. Not only is your question posted in the correct forum, you'll quickly receive many more responses.

Thanks everyone. I used your input and I was lucky enough to have a successful go of it . The details are over in the 930 forum in case anyone's interested. Not only did I use information on this board to help me choose the right car, but I can find (or ask in this case) tons of valuable info to help me fix and mod the car. This is a great community. I hope this thread helps somebody else in the future.
