2004 IMS Difference?

[lfhunt1]

Hey All:

Quick question for the pros - I was told by a Bert Smith (FL) Porsche sales rep that quote: "the 2004 911 IMS bearing issue was re engineered (on the 04's) and that the IMS issue was corrected by using a new larger bearing unit (Porsche made....)."

Huh?? Whiskey. Tango. Foxtrot....

Is this true or just complete salesman BS? I have NEVER read or heard of anything about this.... Thoughts??

Thanks in advance -

More like on the 2005 and it seems to be a running change so some later build '05 have larger bearing. Larger bearing cannot be changed without total engine teardown. They have also had failures. The only way this 2004 would have the larger bearing is if it has a Porsche remanufactured replacement engine.

Porsche finally definitively addressed the IMSB in 2009 by designing the IMS out of the engine.
There are more robust bearings that can be mounted in 2004 and earlier engines.

Perhaps you (or they) should tell the customers we have seen with the 06 (and later) car that lost engines when the "perfected" IMS bearing crapped out.................I’m sure they would be very reassured (or consoled) by the comment…..

The 06 and later IMSB is supposed to be a much better bearing with far fewer failures. You still see one from time to time.
