The number of ims-related engine failures where the original bearing was already replaced with a new one, be it the LNE or some other, is probably a rounding error.

I guess you can see what my advice would be. Short of simply getting it done I might look into installing the LNE Guardian in the dash that warns of impending doom.

I had my IMS replaced when it was clutch time but in retrospect I would have done it pre-emptively anyway.
You're talking about a day at the shop vs. worrying until the clutch wears out.
For me, it's simply not worth having that on my mind just to milk every last mile out of a $600 clutch part. And once you've put in a new clutch, you have a new clutch. utility.
New water pump should also be on the agenda if you're looking at the big picture.
