If this is a standard touring engine, i would make up a suitable patch, and drill and tap water jacket 4 or 2 ba in a few places round the edge of the patch, and screw it on on a bed of epoxy/araldite/silicone. Not the answer for a customer's race engine, but what have you got to loose exactly? Held water on a cracked corner on a vintage Meadows block no prob for 20000 hard miles......W
