I JB welded a couple cracks I had with good results so far. 4 weeks and counting. May just replace it down the road if necessary.

Super common problem. You can weld it....but it will eventually crack again. It's better to replace it with the upgraded design (all over Ebay, etc.....it has expansion/accordian joints). But if you can reach the crack with your welder, it's a cheap temp fix.
