copper flakes in oil

hey guys. heres the deal. i did a 70k oil change on saturday and noticed some very thin tiny flakes on the funnel the oil drained into. i also noticed this last year 5000 miles ago when i changed the oil. the truck has no issues nor knocks or loss of power. and i inspected the oil filter inside and out and found nothing and nothing in the filter housing. my thoughts are

truck sits alot and possibly since the crank is dry its flaking it off the main bearings?

one diesel tech said my main bearings are blown and everyone else says its fine.

any thoughts? experiences?

If they're aluminum, and not copper, it could be a sign of your low-pressure oil pump going.

I had this happen - a lifter broke apart and sent some pins throught the pump and eroded away the aluminum cover of the pump, sending aluminum shavings straight to the first stop - the oil filter housing. Eventually (like, very quickly actually) the pump stopped working altogether. I'm just glad I caught it before my camshaft got fried...

Best of luck.

theres many parts that can do something like that. however over a year ago, my hpop gernaded on a 2k mi round trip half way into it. swapped it out and got to the destination, changed oil and saw the copper flakes to in the oil. that happend to go through injectors too.

so do a blackstone oil test asap on the next oil change and send it off.

Maybe get a real oil pressure gauge, the dummy gauge is just a switch that proves theres at least 7 psi. W/ a real gauge you can get a better idea of where your mains may stand. My experience has shown bad mains will cause low oil pressure readings, especially at idle.

im thinking since i barely drive it the main get dry or not as lubed as a daily driver and its just excess that flakes off. they are very minor and do not make it to my filter. ill send a sample anyway. im certain the flakes are copper, a ford master mechanic said my main was blown lol but yet theres no actual negative signs of a blown main and the oil filter housing is clean. the mord master mechanic says its a mystery lmao

it may also be from my drain plug, the brass copper whatever ring maybe flaking and the oil pushes it into the funnel?
