I don't know, so I am asking....Aluminum particles are soft and small, what kind of problem could they cause in an engine? If he changes the oil very frequently in this burn in situation would not most of them come out in the oil pan?

I recently replaced my time gear with a bronze one, I considered Aluminum but chose Bronze because of durability. Maybe I should Have Chosen the original material to prevent harmful metal particles from circulating around My engine. My crank gear seem to be in good shape so I didn't even try to replace it.
