None of it is ferrous though; I always check with a strong magnet.

Yeah that's a great recommendations to change @ 5k thanks.

However, if the engine was apart recently, even more than one oil change ago, this can arise from the normal shedding of material an engine that was opened up and closed up again sheds.

The older the motor, the more frequently I change the oil.

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.

Changed the oil and filter yesterday at 113886 miles. Cut open the filter and did a good inspection for signs of ims failure. Only saw 3 metal fragments smaller than. 07 pencil lead. Bought the car used and always serviced at the Dealer as I have all service records. Car purrs like a kitten and no noise what so ever driving. Just wondering thoughts on filter find and condition. Thanks!
Where the metal fragments aluminum or steel/iron?
Really doesn't make any difference. No one in his right mind would tear down an engine with 113K miles that purrs like a kitten based on a couple of tiny metal fragments.
Even engines with 113K miles shed metal.
There are not many places that can shed iron/steel pieces so I'm guessing the metal is aluminum. A tiny piece of aluminum will after going through the high pressure oil pump will be flattened out and possibly broken up into several smaller pieces, flakes actually.
Sincerely,
Macster.
+1 That's a whole lotta miles/time/moisture/contaminants on that oil. I'd change it every 5k miles/6 months (whatever comes first) going forward if I were you.
The older the motor, the more frequently I change the oil. 5K would be my max on a motor with that many miles.
Glad to hear it's running so well though.
Pelican Parts is a source for your magnetic drain plug
900-219-009-30-M835 Billet Aluminum Hard Anodized Magnetic Bigfoot Drain Plug (NOTE: Does not include 900-123-106-30 sealing rings), 996 Carrera 2/4 (1999-04) $25.75
Not sure what benefit a magnetic drain plug offers. The filter catches any ferrous metal bits along with non-ferrous and plastic, etc. bits as well.
It is not like a healthy engine sheds enough ferrous metal to make a magnetic drain plug pay for itself by trapping the metal bits before they go through the high pressure oil pump and are trapped by the filter.
Another concern I have with a magnetic drain plug is if it traps some metal particiles, enough of them that the form a blob of metal particles, this blob can tear loose from the drain plug and then it is ingested by the high pressure oil pump.
It is one thing to feed a high pressure oil pump a tiny bit of metal once in a great while. It is another thing entirely to feed it a big blob of the stuff in one gulp, so to speak.
Sincerely,
Macster.
The plug was designed by LNE. It is supposed to give you some warning if a IMS bearing is on the way out. Metal on plug = IMS retrofit or engine death. Bearings start wearing and leaving metal frags before totally failing.
And that magnetic plug from LNE is REALLY strong too - no way will oil flow dislodge any metal particles attached to it....
But there again, theres not much ferrous metal in a M96 engine either....
I have a couple of those flat Al flakes in my filter every time I change the oil too. Usually just one or two. I also have hard plastic bits which I'm assuming are carbon or something. None of it is ferrous though; I always check with a strong magnet.
Cutting open the filter is a good habit, but it seems that the tiny Al flakes are pretty common on these engines. I think they are made by the valve train somewhere?
Based on the LNE site, plastic bits could be bad. IMS bearing seals going bad can leave plastic debris in the filter. Might be first showing of bearing going out. If you start seeing ferrous, time for IMS retrofit.
May be time to do a qualitative oil analysis. The LN Eng retrofit does not increase or improve oil flow to the known-to-be sparsely oiled IMS bearing area. It would appear that this is why Porsche selected a sealed bearing.
If the plastic bits are very hard (not easily dented with a pointed screwdriver) then the plastic can be from the chain guides. This means that it might time for some new chain tensioners as opposed to a new IMS bearing.
Honestly that doesn't look bad at all.
Inside, exposed to the oil, these egines have a huge amount of surface area and almost all of it is aluminum. Over the miles a tiny piece of alum. can come loose and after a tiny piece of alum. goes through at least the high pressure oil pump (gear pump) this can flatten out the alum. into a flake and the flake will almost certainly break up into smaller pieces.
The darker bits if soft can be some internal engine sealer. Some engine castings are assembled sans gaskets but instead sealant is use. For instance, the camshaft covers use a sealant.
If the sealant is not applied just so when the cover is bolted down some of this sealant sqeezes out and is exposed to the oil splash.
Over time age and heat and the oil splash will break these bits of sealant loose and they end up in the oil.
Now if the darker bits are hard, they can be composite plastic from the chain guide/tensioner rails. A tiny number of small bits is nothing to worry about.
If the darker bits are hard and sort of a rubber-like material they can be (can be) from the IMS bearing seal coming apart.
However, if the engine was apart recently, even more than one oil change ago, this can arise from the normal shedding of material an engine that was opened up and closed up again sheds.
Sincerely,
Macster.
There is a lot of different kinds of metal in these engines, as others have said. Yes, the filter should catch all of it, but there is something to be said about using drain plug magnets to catch iron particles. I just bought drain plug magnets from Dimple.
Dimple Drain Plug Magnets
. They cost about $30 each.
There are a lot of videos, tests and other stuff to read on their website. Their magnets, IMHO, are better than most of them on the market. They have them in all sizes and shapes. The ones from LNEngineering may be strong, but they are only available in one size, and only for the 996NA engine. They wouldn't work on my Turbo.
Also, as a "gift", they include a thread pitch gauge with the magnets that you buy.
And, as far as having a "glob" of iron filings break loose and float off into your oil . . . . . not gonna happen with the Dimple magnets. I can lift a 10 pound wrench with the magnet on my drain plug. Iron filings aren't going to break off of this magnet.
