Well, when the WP does fail you're likely to warp a head and/or pop a gasket at which point, for the 2.5l motors anyway, the car's pretty much toasted.

I also suspect that they do indeed slowly go bad, loosing fins over time 'till the whole, now unbalanced, lump comes apart.

I'd say getting the thing replaced as soon as you've got any doubts about it is money well spent!
