[Detrey93]

Hey there!

I wonder if anyone can help

My 164's Exhaust manifold is on the way out and if i cant get it repaired i'm gonna need a replacement... Any ideas on how one would obtain such an object?

Thanks Guys!

Exactly what do you mean and a pic' would be helpful. They can be welded up.

The manifolds can be repaired, like previously mentioned. I think they can be welded or brazed. But, if you're still looking for a replacement...

Is your manifold cracked ? or is it just damaged threads on the studs ?
Crack can be reapired by drilling a hole at each end of the crack , heating the whole manfold & brazing the crack closed . Allow the whole manifold to cool slowly to reduce thermal stresses otherwise it will fracture . If it is simply knackered studs m ask local machine shop for heat & remove or drill out & re-thread the manifold . My last broken cast iron manifold i repaired , i placed over a charcoal bbq after bolting it to a scrap cylinder head , let the whole lot heat up for a few hours , then brazed everything . After that , the bbq was allowed to burn out & cool naturally . Job done

The welding method mentioned is correct. Cast iron can be welded if heated first. Any decent exhaust shop should be able to do this.

They wouldn't have a clue, and that's the cast iron truth. There might be a blacksmith around that still has the skills though.
There are also specialists listed in some classic car mags but it's mostly word of mouth as to who can do what.

Well, sorry, I have not had to do exhaust work in Britain. I stand corrected.

Have you been able to fix your manifold?

In Cradley Heath we still do this stuff. There's a specialist welder called Stronghold Welding near me who can weld anything.
Can you confirm if it's an injection exhaust manifold or a carburettor inlet/exhaust combined unit? I've had injection exhaust manifolds crack but not carb ones. The problems I've had with latter have been a) warping of the whole unit and/or b) leaking at the head seal on cylinder 6 exhaust port. The leakage leads to the mating surface being eaten away, sometimes beyond the point where it can be skimmed.
I may (repeat, may) have a carb manifold kicking around in the yard although these could all have had the problems indicated above. PM me.
Incidentally, I remember a successful repair of a cracked injection exhaust manifold by brazing.
