Shavings from old failed IMS (??) now showing up?

Isn't "drop the motor" the last step in every possible path through the official KK 996 Troubleshooting Flowchart?
I think your heart's in the right place, but it still doesn't make OP feel any better about getting kicked in the ribs. Maybe a thread about metal in the oil isn't the best time for you to explain how stupid you think someone is...

No one can tell you what YOU should do. We can only give our opinions on what we would do.
I can tell you exactly what I would do. I would drop the engine and begin to disassamble it to check for damged/worn internals. Clean/repair/replace parts as needed. Install and be done.
Sorry to harp on this but if you DONT have mechanic ability why on earth buy a car that had metal in the oil in the first place? You are finding out the hard way, rebuilding the M96 aint cheap.

Do a search for "flakes in oil", "metal in oil", etc. You'll probably get hundreds of hits. Most of those people are probably still driving the car today, unless they went into a forum induced panic and dumped it at Carmax. Engines wear, and a byproduct of that wear is metallic particles that are swept away by the oil and captured by the filter, which is doing its job BTW. If you cut open most oil filters on any vehicle or run a magnetic drain plug you will likely find some amount of metallic residue. You are assuming that it is IMS related, but have no facts to back that up. Contrary to what you read here, every M96 isn't destined to grenade into a million pieces. I have owned five M96 powered Porsches with between 60k and 85k, all were on their original IMS. Only my current car has had the IMS done by the previous owner at 90k. Yes, a stock M96 can make it to 90k.
If you are really stressed you could change/inspect the filter again and send the oil in for analysis, at least that provides you with some data. But what then? You really have two choices:
1. Tear down an engine that is running well. At that point you might as well rebuild it to some extent, because it's already out of the car and apart and that's not cheap. So thousands of dollars later you have an engine that is running well. Not sure you've accomplished much, except spent a lot of money.
2. Drive the damn thing. Monitor the condition like you would any other car. If it blows up, spend marginally more money than option #1 assuming some parts are now outside of spec for a rebuild.
Put on your rational thinking hat, ignore the forum IMS frenzy, and really think this through.

I agree with your mechanics then that the best course of action now is to drive it and monitor the oil filter frequently and hope the shedding will subside (in case it was shedded prior to the IMSB retro).
Also +1 on magnetic drain plug like SCHELL suggested. I would also consider Jake's spin-on filter that filters 100% of the oil.
Of course if something is actively shedding metal then none of the above will help but we don't know that yet.
Oh yea, also keep your ears open for ANY abnormal engine noise, idling or at speed.

The spin-on adapter...hm. If you install it, all of the oil is sure to be filtered...but you won't be able to (easily) inspect the contents of the filter. The spin-on filter definitely won't hurt, but it will make it tougher to see if it's still shedding.

Yea, all you need is a filter cutter though. Can always revert back to factory filter system if the shedding subsides later anyway.

Collect the metal in the filter and have it analyzed.
It might give you insight to wear it came from.

Definitely. That's pretty standard.

Come to think about it, you could also install an IMS guardian jr that will monitor in real-time for you. You already have the pan cleaned and hose flakes are probably not enough to set it off. A false alarm is still bettern than a blown engine anyway.

I already know it's shiny, silver, and ferrous, so it's almost certain to be steel. Oil analysis won't help identify the source. The condition of the oil would seem to be a different issue, unless it identifies an internal leak or something (mixing water, fuel, etc. into the oil). Still, an oil analysis every so often is not a bad idea. I have a couple of Blackstone containers on the shelf.
