Cherokee John

2000 Cherokee Sport 4.0L 125,000 miles.

Exhaust Manifold Crack
(low- not at Cyl.Head)

...Could this have been caused by pressuring washing w/engine running?

I believe this is the cast design.

What is the recommended replacement?

1) MoPar OEM (expensive?)
Is there a better steel version from MoPar?

2) Aftermarket OEM style replacement?
Any better than MoPar?

3) Aftermarket Header?
Cheaper/Better durability than Cast?
Brand/Style/Source?

Mechanic friend said he'd replace mine for $160 labor.
I replaced one on a '90 Cherokee and this was not a fun job
(replaced OEM cast manf. w/Pacesetter Header).


Thanks for your input!

I'd recommend you have a good muffler shop do it. When/if a bolt snaps off, they'll have a better chance of fixing it than you.

I've got the same problem with an F350 V10 right now. It's going to the shop later this week because I'm about 100% sure one or more bolts will shear off and they've got lots of experience dealing with it - probably see one a month on V10's alone.

If it cant be welded, I would just pick up a header.
