Well, it's cracked. How bad is it?

Feeling pretty sick over here. Was attempting to remove the remnants of a broken dipstick tube. Tried a screw, a drill bit, and an easy out with little luck. Already frustrated, I noticed this in the dipstick tube passage. My heart sank.

Is it as bad as I'm afraid that it is? Can it be repaired? I have some JB weld if that might be an option.

Any advice or ideas? Pretty stressed at the moment.
