Take the bolt out. Brake clean the piss out of it. Use quick steel not jb weld. Retap it. Stronger then new. We use quick steel on intake mainfolds and crap when porting them out not problems at all. Guy w a rotary has fixed 4 blocks that I've seen with it no problems at al

use a dowel the size of the bolt shaft without the thread, quick steel as mentioned, carve it out with a dremel to bring it back to the original shape (exterior) then remove the rod and tap a new thread. quick steel is the bomb for engine cases, as long as it is not structural. It also fills engine case rash damage like superglue :-)

edit: and get a new bolt, yours has red hair, and thus no soul.

Don't use metal to plug hole. It will become a permanent fixture, dowel can easily be drilled if necessary
