When you have the BB open plug up any holes in the frame including other side of the BB, rig up a BB size plug on the air chuck on your air compressor, put some soap water over the suspect area and put some air pressure (don't need much) inside the frame. No bubbles= good, bubbles= bad
Mix 1 tablespoon of dish washing detergent into 1 cup of water to create a leak detecting solution. You can also buy a thick commercial solution that does the same thing.
Paint the solution over the suspected crack and apply air from inside the BB shell and look for bubbles coming out.
