exhaust outlet stud replacement

[rverjeeper]

I'm having to replace the exhaust system on my '88 Comanche, 4.0 6cy.

Where the exhaust pipe connects to the exhaust outlet on the engine manifold, there are two press fit studs. Sometime in the vehicle's history, one of the studs had been replaced with a plain bolt and nut, the other appears to be original. I have picked up two new studs for this project.

 

My questions are:

Is there some trick or "procedure" to removing the remaining stud?

Is there some trick or "procedure" to install and press fit new studs?

 

TIA

bang out the old ones with big hammer, and install the new studs with same hammer and a drift.....I just replaced a set on a Renix manifold recently (but the manifold is on the bench, not still in the vehicle).

 

Pricey little suckers those studs are....mine were $5 and some change from the dealership, EACH (and just the studs, no nuts or washers either).

Thanks for the link. I tried the search function, either I get no returns or 300+. I'm going to have to see if there is some search engine suggestions somewhere on this forum

I tried using a hammer w/long metal rod to pound out the one still in the manafold. Tried heating up with a torch. No joy. As it is, the stud was in OK shape, would have preferred to replace both though. A new stud went in where the missing one was without hassle.

I hear you. Could have been worse, no longer available. Having said all that, I have an extra stud if someone needs it.

 

Exhaust system replaced. Driving just fine. Thanks everyone!

Are these studs actually in the manifold or are they in the engine block?

Manifold... best bet for removal is to hit it with an impact hammer. You will have them puppies out in a snap!!!

 

Don't waste your time with the studs.. Just throw in a good nut and bolt and then check that about two tank fulls later. After that it will out live you or the jeep!! :D
