Dispeling M96 engine rumors

"While the LN bearing hasn't been proven better than the factory part by a true measure of "field experience" yet, even if it was only marginally better, the fact that you're replacing the original bearing, with X many years across Y many miles of wear on it, with a new part, is still a lot better than doing nothing. "

Why would I be replacing the IMS bearing? Is it in the maintenance manual as preventative care?

It's not in the maintenance book as preventative care, but perhaps it should be. Seems like lately almost all the engine failures are from the IMS bearing failing. It's just not a good design on Porsche's behalf.
