I realize that this would have been much easier done before the motor went back in, BUT is it even possible to replace the gaskets/studs without having to pull a bunch of off and out?

Mine broke multiple bolts so be prepared it was a big PIA
of course mine lives in salt 6 months of the year

Thanks for the link to the vid. I think I may wait for a while till the weather here cools off a bit. The bolts on mine are pretty rusty so I'm sure its gonna be a PITA to do.

use the dermal tool I just got one from Lowes the Blue Hawk brand was $40.00 for the kit I picked it because it has a flex lead for it, and the reviews were good.

I would use plenty of PB Blaster or a good penetrant to aid in removing the studs and bolts

I also ordered a set of SS studs and nuts off of e-bay for replacing the original studs and nuts

Thanks for the help and advice. I'll get to this soon I reckon. The sound is annoying me to death.

My dad's truck pretty much has the manifold hanging loose on one side. Sounds like a tractor but still drives fine.

We tried to do the other side on his last winter but the main problem we ran into was not having the room to weld a nut onto the studs that snapped off. Also it is very time consuming. We towed it to an exhaust shop that was able to complete the job for about 400 bucks. They want 500 for start to finish with replacing all studs.

My 98 EB manifold gasket is also leaking on the driver side. I think the main cause was the catalytic converters were getting plugged and creating too much back pressure. Not looking forward to replacing as it needs a full exhaust replacement from manifold gaskets on back.

I also completely relied on a Dremel tool with remote cable drive and plenty of cut off wheels to get manifolds off my '97 5.4. Luckily, only broke one stud. After years of heat cycles here in the Northeast,
they rust into one blob. The nuts no longer have any shape for any kind of wrench or vise grip to grab.
There's no room for a regular air tool/ grinder to reach and you've got to be careful with the torch. Only advantage is that, compared to my '05 three valve heads in 2nd Gen, there's alot more room to work. And there is more abundance in aftermarket stainless shorty headers, which is the way to go with replacements, along with stainless fasteners that the factory should have put in to begin with. I dread the day when I have to do this to my '05. And, there seems to be only one Gibson SS shorty available for this engine and it's over $700 bucks.
