My '98 Sahara has a noisy exhaust leak that quiets down after a couple of minutes.
This is a used Jeep that I bought about a year and a half ago. After my neighbor
complained I investigated. The fasteners around the exhaust port for the #6
cylinder are missing. There should be a bolt and washer on the top together
with a stud and nut on the bottom. The parts guy said "those studs are known to
break" and, sure enough, he's right. I can probe The remains of the stud just
below the level of its threaded hole.

Q1: Is there any hope of replacing the stud with the engine in the Jeep.

Q2: What happens to lazy people who simply replace the bolt and ignore the
broken stud?

 

Your '98 Wrangler is NOT a V6. There are NO Wrangler models with a V6 motor.

Hard to say. You have to drill out the old stud and use an extractor to get it out.
If you have enough room for the drill (or a drill with a 90 degree adaptor)
or possibly a dremmel, and the extractor, then yes. Otherwise your stuck with
having to do one of two things.
1) remove the engine
2) remove the head
Both of those are almost equal pains.

On the 93ZJ I can say the last stud can't be done in the engine bay.

Depends on how many threads are left. Most likely it will not hold and
the exahust will leak again.

My 97 had the same issue when I looked into it there was an extended
warrenty to 80K in the exaust manifold I had the dealer replace the two
front bolts at 60K then I had the back ones done at 120K at my local
trustworthy garage.
I don't think it was to expensive to have done.

Thanks Mike S..
