I have just bored, ported and tinkered a rebuilt block fo replace the one we found pourous. Its ready to go back in but in my quest to make a good one I have come across a few blocks at the back of the shed from various places and note that they all have the same failure mode with a crack from the centre stud through to the water way. I was wondering as I always like to have a go, what are the oprtions people have tried and how succsessful have the repairs been. So far my ideas have been.....
-Pay and have the crack laser welded
-Grind out the crack, preheat and have a go with the TIG welder using Sifbronze No8 rods. This has woked in a few other spots we were in but mostly with the steamer.
-CNC a dogbone section out between the holes and make a similar shaped stitch a little undersize. Warm the block up and tap the stitch in.
-Fit a commercially available stitch.
