Hey Guys!

Was putting the exhaust manifold back on my viper this evening and ended up breaking a cylinder stud. It did not break flush with the cylinder but rather flush w/ the manifold. I dont know how it happened. I wasnt even giving it the he-man treatment :-)

I saw a few threads on how to remove it but my question for you is this. This is not to sound lazy but can I get by with just leaving it and not replacing it?
It is the top inside stud on the PTO side.

Just curious? If not, any tips or suggestions that dont include removing the cylinder wounld be appreciated.

Thanks!!
 

try a bolt extractor. (not an easy out) they kinda of look like a thread die. they go in a socket and grab whats left of the stud. work pretty good and should be able to do it with the cyl on.
 
change it ...exhaust leak can cause the piston to melt from air leak ....you say its is flush with the manifold ...if you remove the manifold is there enough to grab it with a small pair of vise grips or a small pipe wrench ?..or if you got a welder you can weld a nut to whats left of the stud and use a wrench to unthread it ..since you already had it out should come out fairly easy just hope you didnt cross thread it ....a easy out is always a option but i know the angle will make it almost impossable to drill it centered with out the bit walking on you ....mig weld a nut would probally be the best way cause that will heat it up also ....just be sure to use heat while trying to remove it ...good luck keep us posted ...
 
A viper I bought had a burn down because the owner before me messed up the studs and didn't correct it the right way. Air was leaking between the exhaust manifold and the exhaust port causing a lean burn down. It's worth the extra time to correct this the right way rather then leaving it in.

I hear jeff (staggs) on the bolt extractor but usually have to have about 1/2 inch or more sticking out for the extractor to grab on to but its definately worth a try ...just dont chew the end up so bad you cant get vise grips on the end ...and if you got time and a dremel tool you can grind the stud down flat on 4 sides and make it square for a better bite with vise grips ....
 
Ok. Well it definitly looks as though it needs to be replaced.

I have a buddy with who is a welder to I am going to take the sled to him and see if he would be able to weld a nut on the end and try to back it out that way.

Does anyone know what size the stud is that is in there now so I can get a replacement?

Thanks!
 
The stud may not be to difficult to remove. Have you tried turning it with a vise grip pliers? I would try to to unscrew it first with a vise grip pliers. If that does not work then head the area around the stud with a torch, then hit it wit penetrating oil, repeat this a few times and retry the vise grip pliers.

I have never had one of the studs not come out using this technique.


As others have already said, you must replace this stud to make sure the exhaust is sealed and works properly.
