Looking at the other threads, seems like the size and number of particles in the filter isn't abnormal and the Oil Report seems to say the same. Can any of the experts here really say there is a problem?
2003 911 cabriolet, about 57,000 miles on the motor. Oil and filter was changed about 10,000 miles ago. This is the first filter I've inspected, so seems I should be doing it more often, right?
I hate those cSt and SUS viscosity values. Looks like the classic Mobil 0W40 shearing, since they are on the very low end of the range. You live in CA. Run a high quality, Porsche approved A40 oil in the 5W40 flavor, or run the Mobil 5W50. Also get a magnet billet drain plug from L&N Egnineering.
I think you are losing a bearing. The metal looks like a bearing shell fragment and these have copper. If you haven’t already, you will lose your crank, and maybe a rod and damage your head if you keep driving. The distance between the piston and head at TDC is smaller than the thickness of one bearing shell. Lose a bearing shell and the piston will probably hit the head. You are looking at a total tear down if you want to get all debris out. Continuing to drive will damage some more expensive parts.
The short block deal in the other thread would be a good deal for you, maybe. This would be a good test for what the definition is for an acceptable core.

That's piston skirt coating. It peels off and has a ribbed appearance from the machining marks on the piston skirt (and also why it's not flat and is slightly curved). You are going to have scored cylinders, if not already scored. I would also be concerned you have a bad injector that is leaking fuel. I'd check your fuel trim values for FRA and RKAT. Both should be 1.0 in a perfect world.
The wear levels of all the metals are concerning as well.
For one thing, stop running your oil for 10,000 miles. Start doing 5,000 mile changes.

Yes, now I have the ramps and tools to change the oil myself, I will be doing it more often. Hopefully life will allow more time to drive it going forward

Is this a short fuse bomb? There wasn't that much of the metal/particles and it was a long time to collect them.

Thank you for the ID of the particles, I didn't see anything that looked like this in the other threads. There were maybe 1 or 2 other pieces about the same size in different parts of the filter. Does this amount of material actually indicate a problem? Seems the other materials mentioned in the other threads just pointed to manufacturing/tooling excess being dislodged.
Also, how does leaking fuel cause this to get into the oil? The analysis shows little fuel in the oil.

The previous changes were at the dealer, so not sure what oil or viscosity was used. I put in Mobil 0w40 for this change, but will think about the Mobil 5w50 for the next as usually only drive when it's hot outside.
