What is normal?

[thstone]

Normal is dirty looking oil.

Normal is a few black, yellow, or brown pieces of plastic or rubbery material around the size of a grain of rice.

Normal is a clean oil pan.

Anything more than this isn't normal.

Since you had metal in the oil before changing the IMS bearing, many of the remaining metal particles (metal flour) have continued to circulate in your oil.

With that being said, the sump, filter, and oil all look fairly normal. The metal "flour" should continue to decrease over time but if it doesn't, there really isn't anything that you can do about it.

At this point, continue to change the oil frequently and drive it.
