Nor would the seller disclose this as it would require a steep reduction in the ask. So for the lurkers, be very wary of a car with a recent IMS swap or one with little mileage since the swap. Maybe owners should ask for photos of the bearing from their mechanic at the moment of initial extraction. This can be put in the service records come time to sell the car. Sure this photo evidence can be staged but thats pretty shady stuff that I doubt a shop with a long and well known history would risk for no real profit. On second thought maybe a short video burned to DVD would be better. After all this a $10k plus concern that could give a potential buyer some peace of mind. The shop could charge accordingly.

The proper method of registering an IMS Bearing Retrofit requires the old bearing to be sent back to LN, where it becomes part of a data base.
At the end of the day, from the developer's stand point, any engine that has a bearing failing shouldn't be retrofitted.
If any retrofit bearing fails, no matter if the customer was told or not, it still tarnishes the retrofit reputation. It also has a lot to do with the way the customer is "told" about what **may** happen in the future. If I explain these things to someone, they certainly won't move forward. No unicorns or rainbows here.
If they can't afford to fix it the right way today, before it fails, they damn sure won't be able to afford to repair it after it fails. Then they'll want someone else higher up in the food chain to "stand behind their product". That may be the shop that installed the retrofit bearing, or it may be the retrofit component manufacturer.
Then, they'll be told "NO" and they'll get pissy, then they'll decide to scream about it on a forum... Meanwhile, no one knows the whole backstory.
In my professional classes, I added two hours of info specifically on the topic of pre- qualification prior to an IMSR.

Thinking that's a very fair way to do it as some clients don't have the financial resources to do it up 'the official way'.

Fair to who? Its not fair to the technology or the developers to put these components in harm's way. The people that lack the "financial resources" are the ones who will expect someone else to pay the bill for them. They scream the loudest and whine hardest.
