IMS Replacement L&N EARLY BEARING **FYI
If you have an early replacement L&N IMS bearing, READ THIS
My 2003 996 had its beariing replaced in December of 2014 at 35,559 miles...the car was only driven about 1400 mies after that until I bought it recently at 37,800 miles recently
.
This is from L & N
The bearing was never properly registered with us. It is for certain a Single Row Classic which is the first revision of IMS Retrofit created and publicly offered. It was sold with a 30 day warranty period and has a recommended service interval of 4 years or 50,000 miles, which ever comes first. I would highly recommend having the bearing replaced and upgrading to either the Single Row Pro or the IMS Solution to prevent any sort of failure.
So, ????

It looks pretty clear to me. The clue is "4 years or 50,000 miles". You said the bearing was changed in Dec. 2014 - Dec 2018 was 4 years... The mileage doesn't matter at this point since the time span has been met. The fact that the bearing wasn't registered, means there's a chance (good chance?) that the engine wasn't "qualified" (if you don't understand what this qualification process means, do a search - there's plenty of info here, or go to LN or Flat6 Innovations website for an explanation) before the retrofit was performed. This is an even better reason to replace the bearing sooner rather than later. The retrofit bearing is a maintenance item, The Solution is forever. Good luck

I only posted this to alert EARLY L&N users that they better get their "bearings"...straight.
And perhaps the "EARLY" bearing was too quick on the market?
I will have the bearing on my car replaced in the very near future with a more "substantial" bearing...

I am quite surprised that the service interval was not clear. When I was reading about ims, and the replacement bearing was 4 years or 50000 miles, I know that it will likely be 10 or 15 years before I do 50000 miles. I had my previous toy car 13 years and drove it 37000 km. About 22000 miles. So, with the 996, I would be in to many replacements no where near the mileage. What I would really like to understand is why a bearing has a time service interval? I opted for the Solution. Install price is about the same. $1200 extra for the part plus the extras like the filter adapter.

I'm not sure what the issue here is. All LN bearings, except for the solution, have a service interval. Not sure why they have a time and mileage interval (as opposed to just mileage), but I assume they know their own products.
These service intervals are readily apparent from their website. After confirming that my car had an LN bearing, its the first place I went to learn more about it. I am going to the solution next year when my service interval is up. I won't come near the mileage interval, but why take a chance?

I got the same reply from LN for my retrofit that was installed in 2016. Service interval aside has there ever been a report of an LN bearing failing? I haven't heard of one... But please do tell if there has been.

Somewhere less than 10% of factory IMSB fail.
Yet our aftermarket manf states 5 years replacement even if few miles.
Now, is their bearing better than the factory that has shown in many 996 cars to go hundreds of thousands of miles?
Why does the LN bearing wear out? Is it legal CYA?
Sure like to know the thinking behind LN bearing failure risk after 5 years.

Great fear mongering led by aftermarket parts sellers.
Change your oil, inspect your filter, check cam chain dev., do oil analyst.
Drive it like you stole it.
