Many thanks Bob,

Yes I have some normal JB Weld in the garage, but had not been aware of Somethimg called JB Weld Extreme Heat, supposedly good to 1000F or 537 C and stated as good for manifold cracks??

If it is the manifold cracked, it might be tempting using this first to save pulling Turbo etc. If it fails, then just have to get brother in law to see if he can weld or brake it I think.

Yes I had always thought cast couldn't really be welded, I think specialists do stitch repairs to things like blocks/heads etc. Never needed before so who knows.
T'internet is a bit of a Wild West of opinions as a quick trawl last night returned several posts from someone just using big standard Mig settings to someone using special expensive wire.

Not sure if brother in law has brazing tip or not, would a special rod be needed to braze cast iron??

Cheers
Steve
