Hey guys this is my second post on this app with almost the same problem

So i own a bmw 330i 2006 with the n52 motor inside and bought it used with some problems and i managed to fixed almost all of them excepted this one engine issue that i cant seem to figure out

The engine gives me codes for misfires in multiples cylinders with another misfire code for cylinder 4 and 6

I changed a lot of things in this motor like the spark plugs, coilpacks, maf sensor, oil filter cage and cap, changed an injector, the valvetronic module, both disa valve, all 3 pcv hoses, cleaned the intake and pvc valve, cleaned the vanos sensors

Im starting to be worried that it may be something inside the engine like bad rod bearings and that im chasing a problem that i dont know a lot about

I recently looked at my oil and found some debris in it with some metal chunks, but only the big chunks are magnetic and not the dust that if i understand is not the rod bearing that are usually made out of magntic material( idk correct me if its not true)

I will attach some pictures for support but after trying all of this idk what to attack next and would really appreciate your help

Thank you
