Suggestion
It would probably be cheaper to at least have the chain tensioners checked for missing chunks than it would be to search for ghosts and aliens further down the road.

Suspected cause
In my (troubled, fevered) mind, this seems as likely an explanation for why a crumb of non-metallic debris to appear "semi-ferrous" as microscopic chain debris being embedded in the pad material.

Suggestion · Original poster
The idea of getting them to check their records for the engine and what was done to it has crossed my mind.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.
Check missing chunks than it would be

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

So these were in my oil. They are very dark. Very rough and "slightly ferrous"* Someone tell me what they are.
Bits of something
You can see the largest is 3mm in length. If this nukes my engine, I am putting an electric system in there.
* I say slightly ferrus, because they are attracted to a rare earth magnet, but not like metal shavings which are hard to even separate from a magnet. It is like there is some sort of iron based life form living in my sump, crapping out these little bits.
Ship to MoeMonney, he can fix it.
Not sure what that is, but good luck that it's nothing too serious, oil analysis time.
Is that from the filter, you dropped the pan off to see what's in there?
Tesla swap seems straight forward just check out Speed Academy.
From the pictures it looks like chain tensioner pad material.
9xx Motors in LA do rebuilds for $7,500 if your core is good. They have a great reputation. Check them out.

You can Also go for an FSI Build.
What im working on is completely different. I hope we can offer the 996 community something worth while in the near future.
They aren't sticky (what is your oil like if it is sticky?). When I run a rare earth magnet through the oil, these are magnetically attracted to it, but only just. And this is a dime sized magnet that is difficult to remove from a flat metal surface if it becomes attached.
I am still going with the alien living in my sump. Once I have my oil analysis back, I will get the sump pulled and see what is living in there. If it comes out and takes over the world, my bad.
Water pump &
chain tensioners
are high on my list for servicing. Get
those
suckers refreshed & check your next filter meng. Maybe a sump drop as well to clear out any remaining debris & ensure your pickup tubes are clear?
If your oil isn't sticky enough, you can rectify this by adding a quart of maple syrup to the crankcase. I prefer full-synthetic maple syrup.
Wet objects, for a variety of reasons (surface tension, capillary action, cohesion, adhesion, etc.), tend to adhere to other objects more readily than when they're dry. In my (troubled, fevered) mind, this seems as likely an explanation for why a crumb of non-metallic debris to appear "semi-ferrous" as microscopic chain debris being embedded in the pad material.
Neodymium magnets are strong enough to make even non-ferrous objects do weird crap, though.
More important than whether/why the debris seems attracted to a magnet is whether or not there are larger chunks of pad loose in the engine. The material is hard enough to cause some problems if it winds up in the wrong place. I'd drive something else until I had the chance to confirm that this is not the case.
*edit* I noticed that you're Canadian; I apologize for recommending the use of synthetic maple syrup. I hope you can forgive this casual yet significant breach of international etiquette...we don't all have the same skills with international diplomacy as our Talking-and-Tweeting-Yam-In-Chief.
How much zinc and phosphorus should I have in my maple syrup? I am pretty sure that all synthetic maple syrup is formulated to "cleanse" if you know what I mean.
According to my records, the engine has 15,000Km on it since the last time the pads were changed. They shouldn't be wearing by now...should they? My cam deviation is only +1 and +3...
The car is parked until I have more answers. I am hoping that Jake Raby will chime in with his thoughts.
I have no clue what those chunks of stuff are in your oil....just wanted to weigh in on a "what's this in my oil" thread. LOL. How many miles on the oil? Is this the first time? Not many things magnetic in the engine, except maybe chunks from your crankshaft, a few bearings (unsaid) and pistons/piston rings/rods/rod bolts. Nothing to worry about....
Sorry...not helpful post. I would get an oil analysis and pull the sump plate to see what else is in there. That would at least allow you a visual inspection of the sump, oil pickup screen and internal AOS's (swirl pots) to see what might be going on.
Depending on why they were changed, and if the old ones were already coming apart, could be that you're finding old material that is just now working its way through the engine.
RE: the makeup of synthetic maple - the additive load is mostly corn syrup and food coloring. I believe it's the food coloring that gives fresh motor oil its lovely caramel hue.
Lets say it was carbon, so what does that mean? [edit: it totally crushes like carbon]
PS none of this was in the filter, only in the oil from the sump.
To be honest I'm not too sure, the engine guru
I'm sure will be able to provide some more advice.
Personally I don't think two bits of carbon would warrant a rebuild but maybe two shavings of metal would.
So...drive it 'till it smokes?
The oil has gone for analysis. I will wait for the report before dropping the sump. The mornings have suddenly gotten too cold for the tires anyways.*
*please, no discussions of tires. I would like to restrict this thread to discussions of the Alien living in my oil sump.
Didn't you just have this thing fitting with some sort of IMS upgrade as well? IE a perfectly good engine now on its way out from a questionable procedure?
No. The engine is an MB Motorsports rebuild that was installed by the PO in May 2015. The engine has a "roller bearing" IMS bearing. I don't think my current issues are related to the IMS bearing, but the oil analysis may shed some light on that.
My concern is the whole "carbon" thing. I have records going back to the install. About 15,000km have been put on the engine since the rebuild. During that time, there have been 4 oil changes. So why is there "carbon" in the sump?
I am sticking with my alien theory.

Dear Shirley
It would probably be cheaper to at least have the chain tensioners checked for missing chunks than it would be to search for ghosts and aliens further down the road. If the rebuild reused those parts it could be an issue of regular service. GL with the oil sample & sump drop.
By the way, have you ever been to a Turkish prison? Or any interest in gladiator movies?
Thanks,
Martin (MB Motorsports) reuses a lot of things like poor grammar, useless attacks against Jake Raby and Sneaky Pete, his accomplishments in motorcycle racing, his love for Mobil1 oil, and why the Polish are better at manufacturing bearings, yadda yadda yadda.
Yeah, my review of the complaints against MB Motorsports show them to mainly amount to "I don't like that guy." Probably rightly so.
Still, their website indicates they replace:
"IMS roller bearing upgrade, cylinder head restoration (sanded, resurfaced, pressure check, restored valves, new seals), we install new rod bearings, new main bearings, new piston rings, new gaskets, new seals, new chains, new tensioners, new sliders, new low temp thermostat, new water pump, and much more..."
I am not convinced they are a bad engine builder, just that they have pissed off people on this board.
The oil is off for analysis. When it comes back I will drop the sump and see what is in there. If it is not an alien, but a Polish coal miner, the source of the carbon will be clear.
Why not give Martin a call. Most of what the people on this board complain about has to do with his view on America. Since were in Canada there is no issue
If I were in the position to be needing a 996 engine it would be from Martin long before it came from any of the others out there.
The Oil Analysis has come back. Normal. I realize that normal is all in the trend, but in terms of wear metals, these are well within the "normal" range. If the engine makes it to another oil change, I will send in a virgin oil sample to get baseline numbers. Next step is to pull the sump...
Any comments on the numbers?
Another year, another UOA. My new lab has flagged the "oxidation" number, but wants a virgin sample to compare to. This year there was nothing in the oil, no carbon, no flakes, and no maple syrup. If anyone knows anything about "oxidation" of oil, and particularly the oxidation of DT40, please let me know. Otherwise, please scroll down for UOA p0rn:
