Shortlived Boxster engines survey

[Rob175]

I wonder what percentage of Boxsters NEVER experience an IMS failure? Even if hundreds have experienced failure that might only be a very small percentage......just curious.

I attended a half day program on this subject by a very experienced Porsche aftermarket mechanic in CT last year. Double row bearings some engines (see class action suit to determine which you are) will likely give you a minute or so notice as the first half of the bearing falls apart and makes a racket with the second half keeping the alignment of the shaft in tact. Single row bearings will fail almost instantly, so when you hear it, it could already be too late to save it.

All of these sealed bearings will fail eventually!!! It's a matter of when. And the "when" is a mystery, but over 50,000+ miles makes it more likely. He also said that this is the only application of a sealed bearing inside an engine that he has EVER encountered on any engine anywhere. Thanks, Porsche engineers!!!

The '04 Boxster Spyder I just purchased came thru the PPI with flying colors, boosted by the fact that a new engine was installed by a Porsche dealership in June 2012. The reason for the new engine was a catastrophic IMS Bearing issue at 36,085 miles.
I recently read that all engine replacements after 2006 had the IMS issue addressed and therefore should be a non-issue going forward.
I've been able to acquire the service records of this work and it reads 'replaced with a remanufactured.'
But, in the back of my mind, this issue is still wearing on me a tad.
What do you guys think?
Any and all input would be greatly appreciated. Thanks.
