Metal dust in oil

When I was researching the problem associated with bearing failure, several unfortunate owners posted pictures with a power dusted filter like what you shown. Once they removed the IMS flange and outer seal, this metal powdered substance was also caked around the inside of the bearing and probably circulating all throughout the engine judging what was found in the filter. Most of the engine expects said replacing the bearing and "flushing the system" would not prevent engine failure.

We have a strong consensus that many shops have installed new bearings in failing engines. Even with engines that are still operational, but metal contaminated from a previous failing bearing. This is why Jake Raby requires pre-qualification from certified installers and strongly recommends it to all DiYr's. They have found that installing a fresh IMS bearing in a Porsche engine that is contaminated with metal will not only take out the new bearing, but the engine with it. No winners when that happens... it hurts the owner, the shop's reputation, the bearing manufacturer as well as the patent holder (i.e. Jake Raby).

IMHO, it's best the engine is fully rebuilt and have all parts addressed.

I’m sure that many owners have found metal in their oil, replaced the bearing and flushed the oil, and then either sold the car or kept it. There are a tons of used 996s on the market with aftermarket bearings - no way to tell if they were replaced proactively or reactively, though.
