exhaust studs, broken exhaust stud Options

[rickllyell53]

Hi everyone,
I have a 1973 2.0 that has an exhaust leak. I removed the shroud under the exhaust and could feel the leak somewhere around where the exhaust pipe seats against the cylinder head. The locking nuts used to attach the exhaust pipes were tight and seated so I thought the problem might be the copper gaskets.

While trying to remove the exhaust to inspect, I broke one of the exhaust studs. The locking nut was a thread or so from the end of the stud and the stud broke off leaving a couple threads protruding from the nut. In other words the stud broke near the end of the stud.

To get the stud out, I tried double nutting, but, there wasn't adequate threads to install two nuts.

So the $6 question, has anyone had this problem and how did you remove the stud?

Also does the factory put lock-tite on these studs?
Thanks in advance for the help.
Rick
