cast welding
Got a cast manifold to try and weld. It`s a four branch off my Accord. Lovely crack all the way round a branch. I have cast iron rods so I thought to
heat it and have a go after filing a little groove to let some filler rod in. Keep it hot as it cools. It`s worth a try as a new one from Honda is
275+vat. Found one after much searching in a breakers and guess what?

Brazing works quite well on cast iron.
Years ago I made some V6 manifolds for a cortina out of cut down corsair V4 manifolds all brazed together..Worked a treat!

You can also arc weld cast if you use a rod for cast and heat the manifold up first with oxy-acet.

I had two big cracks in the cast manifold of my MK2 Golf. Both along each face of cylinder no.3.
As instructed here by Mark Allanson I ground out a groove along the length of the crack about 2-3mm deep. Then ground the rust off the surrounding
area, then just whacked the welder up to full and filled the groove with weld.
Have done about 6000 miles since and all appears fine still.
Cheers,
James
