I change these out for a living, and the retrofit process is designed to be a proactive step, not a reactive one. Of all the bearings we have pulled, probably 95% were in good shape. But that does not mean anything, as the time frame from when one starts to go, to when it totally fails is not a big one; once on their way, these things crap out really fast, which is why they give little if any warning to owners.

JEP in PA,

I recently bought a replacement 2.5L with 84K miles on it the listing said "it has already the IMS updated to the new Porsche factory IMS." What does this mean to me? Am I safe to not replace the current IMS?

While this engine should be a dual row, it also means it has the same factory bearing in it, only newer. If it were mine, I would put one of the ceramic hybrid's or even the IMS Solution in it before putting it in the car.
