[Grumpy old man]

Junk it , it's not worth the time to even attempt to repair it . And JB weld will do nothing for it . Sometimes things just aren't worth trying to repair . it's done .

They'll be plenty of comments on how someone fixed one with JB weld or using Belzona but repairs like that don't last and may work for awhile on a farm truck or tractor where if it does get worse you'll just have to tow it to the barn , It's not like it's a numbers matching rare engine , And I'd have a hard time driving it anywhere knowing it had an issue that one day may leave you seriously stranded on the side of the road .
