Well, they are rubber hoses, they get hard with age, crack eventually. You may want to keep an eye, when they start to crack definitely time to replace if not before. They only carry air so even if they leak, the PCV leaks are not that noticeable.

fwiw, the engines on a 240/740/940 do not actually have a PCV valve, rather, they have an oil trap aka flame trap that vents into the intake air... these traps have to be cleaned periodically, as when they gum up, excess crankcase pressure can blow oil seals (typically, the camshaft seal).
