Exhaust manifold stud, '98 Wrangler V6

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..
