a temporary fix is only temporary until it isn't
if this is going to be your daily driver, fix it properly. to me that would be a timesert or other threaded type insert, not JB weld. ideally, though, pulling the cover and repairing or replacing it would be the best option. however, going slow and steady with hand tools, grease and a steady hand you could minimize the risk of metal in the motor if you don't want to commit a saturday to that job.
