    What is the root cause of these IMS failures and has Porsche made corrected parts available for replacement?

  • Look at the previous post here on this subject. Also, we have a detailed feature coming up in the next issue of Total 911.

    I am looking at purchasing a 996TT from the 2002 to 2004 model years. I like the look and obviously many other things about the cars, but do not which to purchase a car that inherently contains the IMS engineering defect (or call it what you wish). I just don’t want to spend a lot of money on a car that will be a money pit. I am considering cars that include the X-50 upgrade or the Ruf upgrade but if the basic engine inherently has problems, do these upgrades make a difference? What might you suggest? Is there a better year out there with a similar body style that has had the engineering problem resolved during design and prior to manufacture?

    THank you

    can someone tell me what the failure of the intermediate shaft bearing sounds like. i was driving last night, went to pass someone, and as the engine revved up i felt a sudden decrease in power. i thought it was the rev limiter. about an hour down the freeway i pulled over for gas and heard a tapping sound out of the engine. any thoughts on this? tom.
