Cracked exhaust manifold

Post by Malcolm B »

1984 turbo has cracked exhaust manifold at the top.
Anybody know if it can be repaired with welding.
Alternatively anyone got one for sale.

I'm not an expert but I guess it depends on how far the crack has developed. You might have some luck trying to repair it but used ones on ebay are quite cheap.

lol.

This is funny because mine did the same thing years and years ago and another guy I knew who had a turbo, happened to him too.

So remove the whole thing and using a 3-corner (triangular file) file, start using the edges of the file and file in the crack all the way around making a V groove. Then get it welded and file the bead down and hit the manifold with some steel wool and a light coat of hi-temp flat black paint and good as new.
