The welds just don't hold for very long, usually they just crack
right next to the new weld. I have yet to hear of any reworked header
lasting.

Well, getting at the header isn't hard if you have a good selection of extensions
and a swivel or two. I got the header off on mine with just a wrench.

(from a prior email to the ZJ list digest)

There is lots of room but watch the torque spec. It's 24 ft.lbs on
all but the outer two bolts that get 17. Too much out there and you
risk distorting the block, it's thin at those spots.

Used a squirt of PB blaster on the bolts before removing but even
then it only took a box wrench to get them out. You don't even have
to remove the fuel rail if your careful.

Order and torque spec

9 8 3 10 11
6 4 2 1 5 7

1-5 24 ft.lbs
6-7 17 ft.lbs
8-11 24 ft.lbs

with the banks your not going to get a torque wrench on #1 no matter
how hard you try. I used a box wrench and reached in between the
header and block.

If you do pull the rail, replace the injector O rings, NAPA has the
parts (three bags) for about 9$. A little spit on the rings helps
them slide into the head and the rail. Fit to the rail first then
evenly work the assembly into the intake manifold.

Re: 4.0 manifold crack !
 
OK, now you got me wondering, would the header be that much better than the
stock stainless manifold you sent a link for? ( which they plenty of in
stock- we sell plenty of those was the reply)
Also, my used warranty may cover this!! Now here is the kicker - may have to
trailer it to the dealer. BECAUSE IF I DRIVE IT IN * IT WILL BE OUT OF
WARRANTY * OVER IN MILEAGE* TALK ABOUT A CLOSE CALL.
