Most of those with failures are the 2005s that still had the old 996-style bearing in an M96 block. The 987 all had the M97 block with the updated IMS design, the base 997 got the same bearing design in an M96 designated block in late 2005, and the 997S got an M97 block at the same time. I can't recall seeing an IMS failure in a later 987 or 997 with the updated bearing. Not saying that it has NEVER happened, but I think it's very rare.
