Cracked RS2 exhaust manifiold

[chancha]

Hi Guys, been offered an RS2 exhaust manifold (thanks Sal) which appears to have some cracks in it. My question to everyone is this; is it worth the hassle in getting it repaired or do I bite the bullet and order a new one?

Stitch welding of cast Iron exhausts, engine blocks etc will cost about £100 at least. There is a company called lockstitch engineering who do this.

I don't know what the cost of a new one is.

How deep are the cracks and in which location? You often get hairline cracks in the collector, these don't appear to cause any problems. You may find it's still OK and wont need welding

still waiting on sal giving me details...........

I've taken a few pics but its hard to see the cracks because they are very thin. There are about 4 cracks in total

heres another

the middle port has a crack in the middle which I think is the collector and there are two cracks on the outer circle part where the turbo bolts onto

sorry should have posted this pic of port 3

The car that the manifold came off drove well and was not lacking in performance.
When switching the engine off after a long drive, I could hear a ticking noise from the engine bay which was probably the manifold contracting as it cooled down

It's hard to tell from the pictures, but those hairline cracks look pretty normal to me. All the RS2 manifolds I've seen have the small cracks on the collector and both my S2 manifolds have the cracks that are on the turbo flange.
