Dave,
There are many wonderful epoxy fillers on the market. I would use a small
Dremel type carbide tool to enlarge the "crack" so that you can see it
properly and then fill it with epoxy. The P block isn't pressurised, but
that area of the casting is a little thin so don't dig too deeply. You can
do the whole job in situ.
Cheers, "Bob".
