Considering there are a number of people that are still spinning bearings, even on 24’s, I would suggest you flush that oil system out asap and invest in a magnetic drain plug. I don’t believe the whole machining debris claim, it sounds more like a design flaw, but we shall see. Two separate factories in two different countries is very questionable. Also, the OEM filter is only rated at 50% efficiency at 20 µm, this is actually kind of crappy considering a good aftermarket filter is 99%.
After you drain the pan pour about 1/2 quart of oil through the motor to help flush the pan. 0w-20 is a poor oil weight choice for that motor in my opinion, but don’t do anything to make them question it or at least tell them. 5w-30 would be my choice. Thin oil and contaminants inherently equals scoring.
