IMSB Concerns

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 ?

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?

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.

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?

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
