Maybe, is there still BP under the cap? I would think that the biggest potential problem would be that the BP for the ejection charge could leak out.

The clay cap serves no function during flight -- they used to use a paper cap to hold in the ejection charge.
I would however be very careful about turning the motor upside down since as RadMan says, you could lose some of the ejection BP. Have you noticed any evidence of BP leakage in your range box (black dust, BP smell) ?
I have flown motors before with apparent gaps and irregularities in the clay caps without ill effects.
I get the impression that clay-cap quality control may not be a big priority with Estes.
Or put a drop of epoxy on it. As long as you don't cover the entire cap, it shouldn't cause any problem.

I would be tempted to dribble a little more 4f down that gap "just in case" and then repack the hole with kitty litter. Blow it up or blow it apart.
Have no fear, Chaos is here.
