I've got a substantial crack and all opinions are to replace rather than weld.
The part number is EDB-8431-A and I just can't seem to find a used one. Any chance the EDB-9431-A would work? (I did come across one of those) Or some other number?

Hi there
I'm guessing that casting number is really EDB-9431-A I believe 9431 means LH exhaust manifold, 9430 means RH exhaust manifold.

There are one or two on e-pay but check carefully as some are cracked and/or welded.
Depending on where the crack is I would grind out with a burr and braze using a pre heat and a slow cool.
I would think someone on the forum might be able to help.
Why are there lots of 9431 but never any 9430?

Thanks Stuey! I hope you're right about the part number, as that would make my life way easier.

I checked my 55 Merc 292 today and it has ECH- 9431- A exhaust manifold,i am sure it is original.The EDB- 9431- A manifold which is probably a 56 will work for you though Carl
