Exhaust Stud broken - help
Permalink  

Okay, I should have known better..

After a few nice trips the exhaust headerpiper was getting loose at the manifold on my 261".

The nut felt like it could be turned and crack I broke the front one of the 2 studs.

The studs are very rusted and the treads gone. There is stil sting ½" of the stud sticking out.

I need some good advice from you.

 

I can proberly get room drill the rest out from below without taking the hole manifold of the engine.

 

I have tried to find new studs on ebay but I will need some help to get the right one.

Can someone help me with a link?.

 

Is another way to deal with it to dril a oversized hole and use a standard hardend bolt?.

Do you have access to a welder? Is there room to get in there with one? If so, weld a nut on the broken stud end and try to turn it out that way. It might take a few trys, but eventually it should work.

If memory serves me right these are the regular 3/8 universal studs, I will check my parts book at work, just depends on the lenght, they are discontinued from GM but I have some new ones here at home, pm me your address and i'll send them off to you.

No question, the best way is to heat the manifold red hot with a torch and either have welded at nut on to the stud that is sticking out, or grab it with a vise grip. I just did 5-6 of them a week ago in a pair of manifolds. I had the manifold glowing right around the stud and it came right out easily, each one.

Heat is your best friend when it comes to rust as the others said heat it up red hot and it should come right out. I have had to heat dolts 2-3 times before they break loose. Get it hot and give it a shot of WD or some thing like that then reheat it and it will come right out with a pair of visegrips. When I was taking the 61 apart I did not break a singe bolt when using this method.

Everything thats been said here & by torch they are refering to Oxy- Acetalyne!!!!. A propane hand held will do nothing but waste propane & expand your vocabulary to BAD words!!!!

Good point Pete. Yes, it has to be enough heat to make the manifold glow orange.

 Yes, heat the manifold around the stud, not the stud itself.

Perfect - thanks!

I found a old stud kit 3/8 x 2.5" with brass nuts on ebay.

Lots of heat and WD40..

I will let you know how it went, in a weeks when the parts are here.

For now I welded a 8 mm bolt with nut on the end of the stud so I can drive the car
