Example of what? You said "I've read about several mechanics installing the IMS Solution". Post #735 doesn't reference the IMS Solution - entirely different product than the Retrofit. A "certified" shop will not install the IMS Solution if the pre-qual fails - metal in the filter is a fail. Here's some info on certified installers:

Always remember that the products (with the exception of the IMS Solution) all have a "recommended time in service" as well as mileage for being serviced. This means that while you may not ever see the 50-75K miles the components are rated for, you can "time out" the product as well.
If you plan to go a very long time (calendar time) with a product, shorten the service intervals and approach with care. Corrosive wear is the thing to avoid, so watching TBN levels in the oil will help with that more than anything.

Hate to say this but once there's metal, they can trap in places only a full tear down can clean up. Have you checked the inside of the sump and see if there are more debris? Despite a new bearing, the lurkering debris can come back and haunt you later.
Add me to the failure list... bought a 2000 996 30k miles in 2015 (Garage Queen). Put 20k miles on it; multiple oil changes; filter busted each time -- no metal; Clutch replacement at 50k miles; IMS Solution ordered (keeping the car); Oil changed about 5k ago -- drained oil -- METAL. I think I caught it in time. Pulling the bearing next week. IMS soltuion arrives Tuesday.

Think I will Buy a lottery ticket!
So... I pulled the bearing; put the flange off to the side; and looked over the bearing and it looked good! I am thinking... where the heck did those flakes come from... nothing from the bearing... tore it apart... looked good inside... damn! No smoking gun... no root cause. Three days later... I thought about the flange.. hmm. Nah.. the bearing internals or race fails, right? Nah... take a look at the photo... Well, that metal went somewhere!
So I think I caught this a just a few short miles before catastrophic failure!

Have you seen that type of imperfection before? If it didn't come from there I am at a loss. Could be something else internal. My option is now is to put it all back together... and check the filter every couple thousand miles. Thoughts?

I hope you're not going to put the same bearing back in...

1998 C2 133000km (80kmiles) IMS bearing replaced with LN Engineering ceramic bearing together with clutch. Bearing came out clean, no issues.
Inspected the bearing today, pulled the seal. The grease was gone, it was lubricated only by engine oil. Bearing itself was still perfectly smooth. Glad I put the ceramic in without the seal, will be good for the rest of the car life.

One thing I have noticed is the car is MUCH smoother now. idles solid, accelerates smoothly... could be the IMS tube empty or the dual mass... either way it is a great improvement.

Repair complete. New Clutch/Flywheel. IMS Soltion installed. I have about 500 miles on it now. One oil change, dropped the pan again, added a deep sump kit -- no metal in the Pan. Changed the oil filter twice since the oil change. Some, ever so slight bits. The last filter inspection hard to notice at all. I will change the oil once more but prognosis is good, I think.
