Have taken the cam back to the grinders. All intake lobes have the same markings , only#2 & #8 intake lobes are damaged.Maybe I caught it in time before they all become like that.
I was curious to see the position & progression of the spalling pattern on a 'mirror offset' lobe. That's not a ton of lube, I'd run that past the grinder for input, best of luck & keep Us posted...
