2002 996 With a 2005 3.6 rebuilt in 2013
I’m looking for some insight. I recently purchased a 2002 996 that had the engine replaced in 2013 with a 2005 3.6 factory rebuilt engine.
I’ve been told that the rebuild after 2006 have a significantly more reliable IMS bearing. Additionally I was told it is much more difficult to replace these later rebuilds.
Any help is greatly appreciated

Have the grease seal removed and flange re-sealed. You'll be good to go.
If it is the single row that can be changed, change it right away while you are there.

Is IMS done based on this note?
Hi There;
I am considering buying this 2003 C4S with 81K miles on it and the owner is not sure if the IMS has been done on it or not, although I see below note from its Carfax report and am wondering if this gives a clue as whether the IMS has been done while they were in there replacing the Clutch or not ? what do you guys think?
He is the second owner and he has had it since 2006; seems to have done all the regular maintenance on it and take care of the car pretty well.

- Front crankshaft oil seal replaced

I had my IMS done to my 2003 C4 cab with only 10k miles on it. Had the SOLUTION done and wanted to keep the old one for an expensive paperweight but I guess they send them to LN engineering for eval! BTW it was perfect no problems but Rab always says its the low mileage ones you have to worry the most about! Upstate imports in Baldwinsville NY did the work. Jeff Thomas great guy to work with! Very knowledgeable. He spent a lot of time with me going over the car for the PPI! Spent 6k for IMS water pump and various other items to get the car where I did not have to worry about it. Found 2 mouse nests in it ! GARAGE queens.

I am looking to get a replacement for my C2 964 in favor of a C4S 996 or 997. There is a lot of opinion on the 996s and early 997(2005-2006) regarding IMS issues. What I am curious about is how many fail after doing the IMS upgrades?
There a guy in our local club that did the upgrade and still had a failure? Any insight anyone could share would be appreciated. Lots of great values out there for 996 C4Ss!

Really need 4 ??
I dwcided if you dont really need 4/all wheel drive, you should not get it, and I do not need it in SoCal.
so I am going to wait for a regular 911 with at least 90k on it already.

Indirectly, this answers your question as to if it is possible for an engine to suffer an IMS failure after the bearing has been changed. The answer is yes. If an engine isn't properly qualified or the new part replaces a failed or failing one, the new bearing can certainly fail, regardless of what type of bearing is used.
We have yet to see any IMS Retrofit fail when properly pre-qualified including zero failures of any of our dual row ceramic hybrid bearings or the IMS Solution.
The exception is with the IMS Solution. I'm not condoning retrofitting engines that have already been compromised, but the IMS Solution has no moving parts sees filtered oil. Positive oiling makes sure debris won't get in there. We've also seen engines that have suffered non-ims related failures and the IMS Solution could be reused, where any ball or roller bearing should not be re-used.

Looking at either a 996 or 986. Many don't yet have the IMS bearing replaced. As a DIYer with a garage (and a lift in the plans), is there a difference in level-of-difficulty in replacing the IMS bearing on a Boxster vs a 911? (And while I'm asking... which car is 'better' as a DIYer in general?). Thanks.
