I had my engine run low on oil for a short time. This locked up a lifter and now I am having all lifters replaced. The machanic recommended changing the cam because of the discoloration. Looks likes normal wear to me.
Check out the picture below..What are your thoughts?
The cam is smooth, no scores etc.

Cam Swap

I believe its time for a new cam. With the discoloration you can also see a wear pattern on the lobes.

Thanks Realz69. I don't feel any wear, but I don't like the discoloration, so I will take your advice and replace.
