Exhaust Leak near drivers side turbo

[bird]

Car is in the garage getting looked at as its meant to be going on a dyno tomorrow.

 

They've said it has quite a bad exhaust leak near the drivers side turbo. Any ideas or thoughts on what it might be???

[Yowser]

Any of the following :

 

Manifold to Head

Turbo to manifold

Downpipe to Turbo

Cat/decat to Downpipe

and if it's the manifold gasket, i've a brand new OEM one left in my garage £7.50 delivered :biggrin:

Gotta be done lol

I had those problems..... the bolt has come loose from the turbo to the downpipe..... apparently a known problem mainly on Aussie zeds ?

Bad news. The manifold is cracked. Anyone know where I can get a greddy manifold that will be right for the td05 16g kit?

 

Thanks,

Yikes not good mate, sadly the Stainless manifolds for these are well known to crack. Later newer versions had support braces welded on them and older versions some peeps made support braces for the manifolds themselves.

 

Being Stainless means you should be able to repair it, do you know exactly what part is cracked? one of the outlets came away from the manifold flange perhaps?

 

Doubt you'll find a spare anyways, if it was me get on the blower to Alunox and fire it down to him. He's the dogs danglies on stainless and in particular manifolds, plus there is a very slim chance he has made a copy of the greddy manifold already.

You got a number mate? Do I assume it's going to be a bomb

http://www.alunox.co.uk/ Leon has done a lot of exhaust and pipe fabrication for Z owners over the years. Top notch quality.

Any local welding firm should be able to fix this problem.

I have another question which will make me sound thick.

 

The likes of Z1 etc do manifolds such as AMS ones. Can i get these type of things or would i have fitting probs etc?

+1 .Any competent welder will be able to repair that..Alot cheaper than a replacement :yes:

[bird]

That'll definately be an option but in trying to cover all basis and expand my knowledge too lol

Anyone??

[jaffa]

do you have 16G turbos and external wastegates? if so, then chances are the other type of manifolds will sit in a different place and could cause you problems

[bird]

Would u be able to tell of I post some pictures up bud?

[jaffa]

yes, they are the external gated ones. Just repair what you have and add bracing to avoid it failing again

Next thick question, how do I add bracing and whY is it exactly

[Smithy]

The Greddy's are some pretty weighty big turbo's and whilst stainless was the popular choice for manifolds, the heating up and cooling down causes stresses on it, the weight of the tubs is always pulling downwards on them too.

There quite a lot of welds on tubular manifolds so it's quite common for 1 or more to split.

By inserting braces points under the tubes where they bend, strengthens them greatly.

It was such a big problem on Zeds in general with stainless manifolds that is why Greg Dupreee developed the Inconnel ones some years ago, but cost around 1K

 

Now yes you could take them to any metal shop have them welded again, however for me i would most definately send them to a guy who builds stainless manifolds all day, develops and designs them, understands the importance of bracing certain ones and better still, knows the configuration of the zeds turbo's.

 

Leon has worked on shit loads of Zeds, he was the guy who I had build all my N/A manifolds when i used to sell them cos he is rated very highly in his field.

Of course your money, your choice mate.
