Previous owner did some work and now I'm feeling the repercussions. I changed out the water pump and I accidentally cracked the timing chain cover. After we got that off, we found that a bolt had been broke off in the block, drilled/tapped, and at some point the ear of the hole had cracked too. Now I need to reinstall the timing cover but one of the holes doesn't have anything for the threads to catch.

This is on a 1995 F150 with a 302. I'm open to suggestions/ideas.

It's the lower left bolt hole that is broken (in the bottom of the "Y" in the photo).
