I would rather have a M96 and replace the IMS bearing w/the ceramic LN bearing. As others have mentioned, a M97 (w/new bearing design) requires the cases split to replace the bearing, an impractical cost for most.
Maybe the lucky guys have the M96 or like me are looking for one that may sell at a discount due to a weaker, but (preferable) replaceable bearing design.

- The early M96 engines have old bearings.
- The later M96 engines have new bearings.
- The early M97 engines have old bearings.

So yes. There have been IMS bearing failures in M97 engines, but those engines had the old-style bearings. I know of no failures (of M96 or M97 engines) from the new style bearings.

There seems to be some conflicting data about which engine #s for M97 have the new bearing. One post says it starts at 68513295, another says it starts at 68509791.
My VIN # falls *outside* of the range, and my engine # is 68512902.
