I don't know much about the 986 yet or engine internals in general, but I don't understand this statement at all. Hopefully someone with more experience will address this comment
After a week of ownership, I ordered then hours later canceled the IMS Guardian. Instead I I decided  to spend the extra money to have the bearing replaced. Peace of mind is worth a lot to me at this point in life.
