This is wrt a Ford/International 7.3 Powerstroke diesel w roller cam and lifters that I am rebuilding. I need to replace the cam due to moisture getting to one set of lobes somehow in storage and causing pitting.
I'm going to price a new one Monday but in the mean time, I was browsing used ones online. The new one is probably very expensive so a nearly perfect used on w minimal wear would work great.
This one is local and very close, I could go grab it in 30 min. round trip. My question is this; every one of these I've looked at photos of has the same type of discoloring(?) on lobes, some lobes worse that others. You can clearly see it in this photo:
All lobes have at least a small stripe in the middle but some have a much wider mark. Is this a big nothing as long as the lobe still feels shine-y or does it mean that it's losing its hardened finish?
Here is the listing w more photos but every one I've seen looks similar or worse. TIA.
