Immediately after purchase, I took my Boxster S directly to have the IMS done...when they pulled the bearing, it was very loose in its housing and when they pulled it apart, the bearings inside were scored and no longer spherical. They said it was one of the worst they've seen and it was ready to go immediately! Certainly makes me not regret the expense! I have a question, though...when I start the car in the morning, I'm very careful with not revving it and keep it under 2k RPM until the temp gauge hits 180...would you all recommend babying it like this until it reaches the operating temp, or is it overkill?
