    That sucks! Time to either look for another block or bring it to the machine shop for magnafluxing and a price on a sleeve for that cylinder.

    Ask them how much it would cost for all that, minus the sleeve, on a good block. For the difference, it may not be worth the hassle of finding another block...

    Just braze it, it'll run forever, or at least until the next WOT shift.

    Brazing is like welding it. It will last a couple passes brazed at the most before sudden self disassembley.
