99 CTD w/ cracked exaust manifold

[Cody]

What do I do? The crack isn't that bad but it's getting worse. I've heard mixed reviews about welding it up. I can't seem to find any aftermarket headers for the diesel (lots of them for the gas motors)--where do I find them? Is stock the only option?

So, how good/bad is it to weld up the little crack? How difficult is it to pull the exaust manifold if I have to put in a new one? IF I do an aftermarket one do I need to do the exaust at the same time?

I believe ATS sells a 3 piece exhaust manifold.

I think ATS has headers.

from the looks of it not to bad. just undo the down pipe, the turbo and the bolts holding the manifold on.

I imagine this would work ok with the factory exhaust..?

from everything I have heard I would have to say yes.

BD makes one too.
Or go see Josh at LHM and see what he can do on new one, then get it HPC'd. They seem to hold up well after coating.

I have heard this as well.

just get 4" exhaust while you are at it, that will lower egts and keep this from happening again. the three piece kit is

Unless you want to weld it every other week you will have to get a new one.... Im cheep and just keep welding mine. You ought to see the amount of booger welds on the damn thing.... I have tried pre heating, nickle rod, mig, ect. None of them work lol.....

As bad as I hate to mention them, ebay always has some at auction and they go cheap.

I found a stock manifold from a 00 3500. I imagine this would work?

I would like to do the 3 piece and a full exhaust, but I just can't swing 800 bucks right now.

It's not too bad to pull the stock exhaust manifold. Me and Jinx replaced his cracked exhaust manifold with the 3-piece ATS one in about 3-4 hours. You can use your stock exhaust...the ATS manifold will bolt right up. Probably the trickiest part is getting the 3-piece manifold together, we just heated up the middle part in the oven for about 20 minutes and then we could slip the sides in. If it were me I would do the ATS manifold now, and then the bigger exhaust later when you can afford it.

is there noticeable performance from the 3piece or just reliability?

From what iv'e read, mostly reliablility. The fact that it's 3 piece allows for expansion and contraction abilities. Haven't talked with anyone who actually has one though. Im just curious to know from those that have had cracked manifolds. How many miles, and was there a pyrometer present? And what temps were seen for how long?

 

[Jinx]

I noticed a little increase in mileage and it seems just a little peppier. I plan on doing the exhaust and a box sooner or later so the ATS 3 piece just made sense.

I hate spending time or cash on something that is going to give me the same headache down the road...

as far as what happened when it went, I was pulling two jeeps up soldier summit at a good clip when the clamp on the turbo boot broke and raised hell with the exhaust manifold and no I didn't have a pyro on it.

along the lines of cool, but not necessarily performance adding, friday i took out my turbo silencer ring.. it sounds so cool at like 15 pounds of boost on the freeway... woooooooosssssssshhhhhhh
it did it on break at work, took about 3 minutes.

I read somewhere in DTR that the holset turbo was designed without having a silencer ring and that it was mainly a dodge issue. Mine has always been more noisy than most other ctds iv'e listened to. I still have mine in. I can hear it whine more now that ive got a AFE stage II. I'm sure I'll take it out eventually.
