I’m sure your’s will last a while, I’ve told myself about fixing things properly that are still running on my bikes today, on the “to do” list. Its just the barrels are made from grey iron and it is brittle (and soft) so you have to be careful winding tight bolts into holes or it may crack. I’ve done this on a head stud last year but luckily it was one of the centre ones so had a decent area around it to seal. It is still together and still water tight today thanks to some good sealer but really I need to take it apart and weld it. Over winter… maybe….
