Unless you have some magic type of cast, I have
not had a manifold that I could not weld . My
guess is they tried it with an arc weld rod,
and that is probably the worst choice. Brazing
is a better choice , but will sometimes let go
due to the heating and cooling as the two do
not expand and contract at the same rate. Best
to weld with torch and cast iron in stick form.
The o/a weld becomes part of the base material
and is the same material therefore expands and
contracts at the same rate.

You get it here and I will repair it. Below
are some photos of before and after and also
a link to more photos.
