Hi everybody. My car had a full stock rebuild less than 100km ago. New crank, bearings, pistons, rods, and rings. I noticed a little bit of glitter in the oil on my dipstick so I decided to take the oil pan off and inspect the bottom end even though the engine wasn't knocking or anything. I found 3 or 4 silver flaked in my oil filter, not mostly just dust. I took off my oil pan and found this.
so I took my rod caps off on cylinders 3 and 4 and the bearings looked like this.
Cylinder 3
And Cylinder 4
Just to clarify if the pictures I'm aren't clear enough I can see at least some copper material on every bearing, with the bearing on the right from cylinder 4 having virtually no silver left on it.
Last question is, fortunately I caught this very early, the engine wasn't making abnormal noises, it was on a basically brand new rebuild, so you wouldn't think this sort of thing would be going on in there but my paranoia got the best of me. Do any of you think I could I get away with just a new crankshaft and bearings, seeing as virtually all of the particulate I have found is very very fine, almost dust? Or will this just happen again if I do that?

there are lines in the crankshaft that I can feel with my fingernail, AI it's toast. My question is what could have caused this. I did at one point drive very gingerly for about 5 minutes with some oil that was somewhat flooded with gasoline, could that cause bearing failure this bad with such low mileage on them.Just to clarify if the pictures I'm aren't clear enough I can see at least some copper material on every bearing, with the bearing on the right from cylinder 4 having virtually no silver left on it.
