Main casting repair

[tayto]

Rebuilding a '78 Turbo Buick 3.8L Qjet and while removing the leaking secondary well plugs a part of the casting where the secondary rods go broke. I am wondering if there is a repair method for this? Welding, soldering? Would it be sufficient to just use Marine Tex to glue the broken piece in place? Hoping the casting is not scrap as finding a core may be an issue.

It doesn't look like there is enough material left to make an effective repair....Cliff

I have the piece that broke off it broke fairly flush. what are my options?

Cliff is the main body alumnium or zinc doe cast? I may try to just solder this piece back into place. Let me know. Thanks.

It will not solder well, it's an cast alloy with zinc in it......

Cliff, I ended up using marinetex to do the repair. did at the same time when I installed the secondary well plugs. I used a digital scale to weigh out the marinetex before I mixed it. have not had luck eyeballing it in the past. let it cure for 24 hours and did the soap&water test this afternoon. So far so good, I hope it will last for a while once put back into service.
