I guess that's my main concern - would a crack in that location affect the alignment of anything internally and cause undue stress or premature wear? I suppose if it did it would only be out a few thou anyways...
If I had to guess, I'd say that weld is 20 or more years old, and I know the last time the truck was used was about 7 years ago so although it may leak, the truck does run. (Should run - once I figure out the lower rad hose issue.)
