Mine was cracked imperceptibly. I chased that gremlin for 4 months before the injection mechanic suggested the housing as the culprit. Apparently, some gorilla-like installer (see avatar) got a little too happy once-upon-a-time when changing the secondary filter cartridge. Pulled one off a 603 at pick and pull and problem was solved. Not the same part on your engine, but I would guess made from a very similar casting.
