This is what I pulled out with my fingers on tearing the engine down.
I got probably 30% more fines out by weight using magnets and solvents.
I went through many cans of carb cleaner, brake cleaner, chem tool, a pint of acetone, a gallon of lacquer thinner (what the heck, it was just sitting on the shelf), lots of hot soapy water with over the top rinses with more hot water, towel drying, followed with a heat gun until no more water was evident, then plenty of WD-40 (displaces water and cuts oil and stops corrosion). The case halves got special attention with non ionic solvents (hydrocarbons), then an ionic solvent with sufactant (soap and water). Many small scrub bushes wooden picks, and a knuckle or two met their maker in cleaning the engine. Every part got a complete dis-assembly and then a poking and prodding into every nook and cranny looking for shavings, and no, I'm not a proctologist, but my car thinks I am.
Of note: look out for commercial "de-greasers" they can contain lye which eats your hands, and etches your oil pan. Cuts the grease great though.
Still, I expect I will find the odd recalcitrant chip that will refuse to leave with its brethren so I'm not too worried to find one or two in the oil filter.
