check the other threads on this topic on the forum, in particular the posts of Jake Raby--an interesting read.

There have been suggestions that more frequent oil changes may help as well as not lugging the engine at low RPM

From what I understand, if the failure is going to happen to your car, there is nothing you can do to prevent it, short of taking the engine apart and putting in a revise bearing assembly along the lines of what Jake has come up with.

The question that has not been answered is why all boxsters with these particular bearing assemblies don't fail in the same relative time frame--say 30-60K miles. It could be due to driving, maintenance habits or that the bearing supplier has terrible QC and these are random failures due to the luck of the draw as which bear goes in your car.

In other words, no one knows for sure outside of Porsche and they aren't talking.
