Yep... Your description matches the layout in my FSM for the 3.9L. I'd
order the OEM studs today and get to work when they are in (you'll need the
appropriate nuts and washers of course). I agree they are probably cheap
(nice change, huh?!) so I'd probably order a full compliment of four (just
in case another one went) or I messed up the threads trying to put it on.
I put my headers on when the truck was only a couple of months old and I
still had to use a lot of liquid wrench/penetrating lubricant. So, I'd
spray the hell out of yours and let it sit for awhile before I tried
anything... I'm talking spray it, wait 5 minutes, spray it again, wait
another 5 minutes and repeat 'till your satisfied you can't possibly get
anymore in there (or your can is empty) then wait 30 minutes to let it
really sink in!
After that I'd give the bolt extractor a try but I would think the key will
be patience, I.E. try to coax it out slowly. Shoot in some more
penetrating lube as your trying to get it out.
Well, that's all the wisdom I can impart! ;~)
Luck!
Tom

<< Stupid me, I deleted your post asking if the exhaust manifolds were
threaded... I finally found where I put mine, and there are no threads in
the bolt holes. Note mines a '98 but I'd be really surprised if they
changed that aspect of the design.
If I were you, I'd get that sheared bolt out and replace it... There was
no gasket between the stock manifold and the block so the seal depends on
those bolts.

Thanks alot Tom, the info is greatly appreciated, especially about the part
about not having a gasket/sealant on those manifolds!! Now the problem is what
will the best/easiest way to get that broken stud out of there? Will simply
spraying it down a couple of times with penetrant and using a bolt extractot
work?????Now that I know the stud has to be threaded into the engine block,
how do I know how far it is threaded into the block??? I guess I could just
order some manifold bolts/studs from the dealer to determine this; as they
shouldn't/cannot be that expensive. I guess what I am trying to determine is
say I get the broken stud out, how far in should I screw the new bolt/stud
into the block??? Here is what kind I see now on my Dak V6 4x4:
*****The pass. side manifold, from the radiator to the firewall, has a stud
wuth a nut; then another stud with a nut, then the remaining 2 are simply bolt
heads.
*****The driver's side manifold, from the radiator to the firewall, the first
2 are bolt heads, followed by a stud with a nut and then the hole closest to
the firewall is the broken one. Is it recessed in the hole about 1/2", if
that.
Or do I assume this bolt/stud will simply have a hex head on it and I will
just tighten it down to the manifold? The other manifold bolts have threads
sticking out and nuts on them or hex/bolt headto keep them tight. How do I
know which type I will need?
THANKS ALOT TO ALL WHO HAVE SUGGESTIONS ON THIS!!!!!!
