Anyone seem marks like this on a camshaft?
Pulled the cam out of my 318 to make some changes,
Anyway, this cam has been in this engine for 15 or so years, but has been run very little, probably 7K miles on it.
So I've never seen this on a cam before, it has circular marks on almost every lobe, and even on a couple of the bearing surfaces. They feel smooth under your finger, but you can catch your fingernail on them. They are all along one side of the cam.
Any ideas on what this is from, or ?
