So far, the new engine is running fine after about 10k miles.
However, I noticed something a little disconcerting. I replaced the stock drain plug with a magnetic one and found a lot of fine metal on the magnet after the first oil change. At the second oil change, I still had fine metal on the magnet albeit much less than before. I should note that these were not big pieces though. When I went to clean off the magnet the metal bits essentially created a silver smear on the paper towel.
I sent the oil out for analysis both times and the results didn't show anything out of the norm. I'm hoping that the next oil change produces even fewer particles on the magnet.
Any thoughts or experience with what I'm seeing here?
I've uploaded a few photos to provide a visual of what I described. The first three photos (white gloves) are from the second oil change with less metal on the magnet. The last two photos (blue gloves) are from the first oil change, which had what appeared to be more metal on the magnet.
