Replace 997.2 and beyond engines and porsche will go back

If successful, this will replace the 997.2 and beyond engines and Porsche will go back to the IMSB design of motors.

If the IMSB fails and you need to replace the engine, it could cost $10,000 or more.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi, I have a MY2005 997 Carrera 3.6L
It is an early 2005 build, so it has the M96 engine.
I purchased the car in 2015 with only 6000 Miles on the odometer, and at present it has around 12000 Miles.
I have never seen any sort of debris in either the oil pan or the filter,
Would it be wise to get the retrofit done proactively? Or has the IMS issue been overhyped to the point where people are doing it just because they are scared?
The engine is at some risk of experiencing a failed IMSB. No one can say for sure what the risk level is.
Even if you address the IMSB with some aftermarket solution the solution may not last as as long as you would hope or the engine could suffer from some other serious internal engine problem that could result in the engine being as dead and worthless as if the IMSB failed.
If you are feeling lucky continue the way you have. Change the oil/filter regularly and don't run the oil too long. 5K miles or every year is good.
Be sure you run an approved oil and one with right viscosity for where you live/drive. For instance if you live/drive where it gets real cold: -25C or colder; Porsche calls for 0w-40 oil to be used to ensure proper lubrication at cold starts.
If the fear of an IMSB failure keeps you awake at nights or causes you to fear the car and not drive it research the IMSB solutions and pick one you feel offers you the best chance to continue to drive the car with no real worries about the IMSB.
Selling a model with the iMSB issue or not buying a model with the IMSB is certainly a solution to the IMSB "problem".
It is my opinion, and has been for some time, that a car with an engine that if I felt needed such a drastic preventative measures done to the engine would not be on my short list of cars I'd own.
Regarding the previous paragraph I note that in 2009 I was not concerned enough about the IMSB issue that I bought a new 2008 Cayman S. Unfortunately due to an accident (not my fault) shortly after I bought the car I never got a chance to see how the car fared over the miles. Still knowing what I know today but were I back in early 2009 I'd still buy the car. I just would not have driven it that fateful night Friday night.
if it keeps you up at night, then go with an IMS Solution and never have to worry bout it again.
I'll stop there and not bring up the bigger issue with these engines.
A percentage of them fail. Enough to cause many people to seek retrofit / aftermarket solutions. Run the numbers and make the decision like you would an insurance policy. The cost of the retrofit (I'd personally recommend the IMS Solution if you go that route) vs. the cost of what happens replacing your engine if it fails. If you can't stomach either cost, this car isn't for you... because even if it never fails there will be expensive parts/repairs at some point.
To OP:
The relative hostility to your question is because this subject has been beaten to death in the 996 forum and the definitive answer is "Where did you say the fish was caught?"
If you like the car, and want to commit to long term ownership.. spend some money on the IMSB
whether it be the Retrofit or the Solution
@ 6000 miles in 10 years, the car screams of garage queen and the
perfect candidate for some attention
however, if your not seeing ferrous particles, why would you risk waiting
for them to appear ?
no guarantee that they will, but why risk a low mileage engine to any type of damage ?
It depends on how you deal with risk. There's less than 10% chance you will have an IMSB problem. If you don't, you saved money. If you make the repair, you're out several thousand dollars. If the IMSB fails and you need to replace the engine, it could cost $10,000 or more. How do you like to roll?
More importantly, how many miles do you plan to put on the car and how long do you want to own it?
I'm a risk taker and didn't do any IMSB on my 2000 Boxster S, and don't plan to do it on my 1999 911.
There is a new carbon fiber and vinyl composite IMS bearing coming out later this year if you can wait for it. And it can also be used in the 997.1 that have the third generation bearing and you don't have to crack the block open to install it. It uses a new liquid insertion technology that surrounds the original bearing with an exoskeletal version of the new bearing. If successful, this will replace the 997.2 and beyond engines and Porsche will go back to the IMSB design of motors.
Lol, yeah, but in all fairness, I kind of played it safe buying a 99 that has the double row IMSB. Those are supposedly more like 1% failure rate. But Murphyslaw is alway around, so best be careful and cut the oil filters open every time
