The email above shows the later IMS bearing in engines from mid 2005 to mid 2009 are still prone to failure. This car was advertised in the UK August 2013, it was a Porsche Boxster S with 27,000 miles and a new engine. The problem with this engine is no one has any idea when the bearing will fail, the sad part is that one small bearing failing can total the engine. No other manufacturer other than Porsche has placed a greased filled fully sealed bearing within the confines of a combustion engine, no one ever anywhere, there is obviousely a reason they don`t do it. Being aware of this fact and knowing previouse upgrades were failing Porsche in their wisdom put the same type of bearing but larger into their engine now making it impossible to upgrade this bearing without a total engine ripdown if it shows signes of failure in the future, which it will. In these later engines If you have a guardian and it indicates the bearing failing, you have to purchase a new IMS shaft and bearing from Porsche and strip the engine down to fit it, this will cost thousands. The best engine in my view is the pre August 2005 with the smaller bearing and a guardian, this bearing can be replaced cheaply.
