Should I or shouldn't I?

THIS question is the one which drove my decision NOT to replace the IMS this time.

Last motor, i took out a perfectly good bearing with 147k miles on it, and replaced it. 5000 miles later I lost the motor to something entirely unrelated.

How many "what-ifs" can I defend against? Where do I draw the line? I buy a 15-20yr-old car, with lots of miles, with unknown service history (sure, you may think documentation tells the story, but it's still a "box of chocolates").. there are literally DOZENS of things that are at least as likely (from a sheer statistical point of view) to take-out this car as the IMS is.

pi$$ on it. I left this one alone.

I did the clutch on the Blue Boxster that I sold to a friend this spring, While the transmission was off I pulled the flywheel, then the IMSB flange (AFTER having locked the timing) and verified the IMSB. It turned smoothly and there was no play. I then pulled the seal off the bearing so that it would get direct oil lubrication. There was no grease in the bearing when I removed the seal. Put it all back together and it has been running fine since.

I've heard about pulling the seal off. I've also wondered about doing the European Parts Solutions procedure of punching a small hole on the other end of the IMS behind the oil pump so to send oil to the bearing. That is IF for some reason I need to remove my Tiptronic.
