Not really; but it is a real and ever present danger for the M96 engine. Some engines go well over 100K miles with the OEM bearing, and never have a problem. Others do not live anywhere near that long. How the car is used does not always appear to come into play; one customer with a 2.7 engine wails the snot out of it every chance he gets; no problems. Another owned by someone that takes immaculate care of the car and drives it in a more normal fashion loses two engines before trading the car for another brand. Another owner that takes equal car but drives the car hard on and off the track has had one fail as well.

Point is that the IMS issue is not fiction, it is not “marketing hype” created to sell remedial products; it is a real problem that gives little (if any) warning prior to failure. And when the IMS bearing does fail, the usual result is a totaled engine. There are no model years that appear exempt from the threat; it just seems to come out of nowhere.

The LN Engineering/Flatsix updates offer an alternative that seems to work, but at a price. Unfortunately, I am not aware of anyone with the upgrade that has gone 100K miles as of yet; but I am also not aware of anyone that has had the upgrade and subsequently had an IMS fail either………………..
