Cam lobe discoloration normal?

Yeah im not sure if its the reflection or not. Without a light they just look polished. Im gonna see if i can find my old drop light and see if it does the same thing

This posted right before my first post and I didn’t see it. They can be shiny, they just can’t be blue. If it’s not blue to your eyes then send it. It can’t have many miles on it because with a hydraulic lifter there will always be a shiny line around the base circle as there is always a load on the lifter.
