Thanks guys, some interesting thoughts there.
I confess I'm struggling a bit to picture how it would be stitched when it's such a narrow area, also perhaps depends which direction the crack(s) is heading. I know this method works on larger castings though so could be worth a phone call.
Loctite 290 sounds interesting. I note the data sheet says :
For Porosity Sealing
1. Clean area and apply localized heat to the area to approximately 121°C.
2. Allow to cool to approximately 85°C and apply the product.
It also has some claimed tolerance for contamination (no way you're getting in there to clean the surfaces).
Encouraging though that no-one yet has reported a block splitting in half...
