Over the years, we have seen engines of all levels of mileage lose their IMS bearings; 10K miles or 110K mile made absolutely NO difference. Once the grease was gone, and no real lubrication was taking place, they died.
When we compiled our data from years of exposure to the issue and did a statistical analysis, mileage show a very low correlation with IMS failure; when we added in the data from two other shops to increase the sample size, it only got worse.

How can it have
nothing to do with mileage?
Yes there have been some that have failed even in higher mileage and daily cars, but seals will fail due to little use resulting in them drying up, which leads to a brittle seal, which cracks and fails. This is far more likely to be found on low milers than ones which are driven daily.
So let's just get this clear a second for everyone:
Are you saying that if one person bought a 14 year old Boxster with 12,000 on the clock, and another person bought a 14 year old model with 120,000 on the clock, the chances of problems with the bearing are going to be the same between both? That blows my mind if you think that.
