"Luckily, most qualified Porsche shops can perform a pre-purchase inspection and identify bearings that have been upgraded or may need to be replaced."
That must be one expensive PPI
Buyer: I want to check and see if the IMSB has been replaced and need to have my mechanic drop the trans to inspect it, OK?
Seller: sure you can take my car apart, no problem
Wow. I gave up as soon as they basically said the double row bearing was crap. I'm glad I stopped as my head might have exploded if I had gotten to that gem...
Why stop there? Why not pull the whole motor apart for a PPI?
There is no statistical proof the replacement IMS bearings work better than the factory original. None. I think it's just placebo and may actually be worst. We will see in 5 to 10 years.
So I get there is a real problem here with a small percentage of the 996 population.... but I just could not resist an pristine 2000 C4 with 36k miles! Reportedly has had the IMSB replaced, yet no documentation. Enter the IMS gaurdian jr. -- inexpensive and makes logical sense. If there is metal in the oil shut it down. Beats a $$$ tranny drop just to look.
Annoying how EVERY article about how great a deal the 996's are winds up mentioning IMS, mass produced interior, water cooling, how "real" Porsche snobs hate it, etc, etc.
EVERY new Porsche 911 is water cooled now, get over that! Mass production? Same, that's how the world has evolved. Ugly headlights? Not as ugly as BMW or Audi headlights! IMS - I read a 1-5% risk.
All other older 911's had their expensive issues. The 996 is faster than all of 'em!
So the author incorrectly indicates that the earlier bearings are most trouble prone, incorrectly suggests that a PPI will reveal whether the bearing has been updated, and then goes on to explain how the extensive aftermarket ecosystem provides dirt cheap replacement parts that make repairs and PM cheaper and easier than working "on a modern Honda."
+1 AndyK! These articles mention the same stupid crap every time. Having said that, I'm assuming the photos posted in the article are Porsche file shots, and they do the 996 no favours. The shots do nothing to flatter the look of the car at all! Much better in person!
