You answered me before I posted lol.. It seems like the retrofit is only a temporary fix from what I'm reading. I thought I read it's good practice to replace that every 5 or so years, just as it would be standard practice to replace the OEM IMS bearing.
My stock bearing is going on 10 years (though I obviously don't know it's condition). If we're being quoted to replace the retrofit around 5 or 6, what's the difference (aside from cost and supporting a community sponsor) in going through Porsche for this particular bit of maintenance, especially when they back it up for 2 years/24k miles?
Thanks again

I'm not saying all will fail this year, but a certain small percentage will. And next year the same. Etc. Until the percentage of engines with failures starts to accumulate to a noticeable number.
Good luck Sok
