I received a picture of the head - the crack is to the point where if
it grows any further there will be definite sealing issues on #2 and
probably #3.B  I like this suggestion - a hole to stop the propagation
and silver solder to seal it back up.B  I'll have to remember that one!

When I went through the "cracked head" issue (mine wasn't
repairable), someone suggested "stitching" which is a series of
threaded plugs run through the crack.B  That's the only other fix that
comes to mind.

Cheers, Tony Drews
