My suggestion would be to first search out and join a local Model A club. There are always a few guys in any club that have "been there" and are a marvelous source of help.

If you came to our club and asked me the same question, I would suggest that you have the crack metal stitched and would offer to do it for you. Unfortunately, it is easier to do the work in that location with the block out of the car. It would make a great Saturday morning "show and tell" tech session for all the club members.

Short of the metal stitching, a good block sealer and a glue "treatment" might serve you well. You may find that the crack doesn't leak as is. Run it and see.
