It started making an unfamiliar noise, valve train frequency except not a hammering like a colapsed lifter, rather a scuffing/sqweeky noise. Removed the belts and looked for vacuum leaks to no avail. Put a tube in my ear and couldn't pin it down to one side or the other so figured its time to look at the cam. I kinda felt i was on borrowed time.

What about the lobe next to it in the first pic. Does that show any evidence of wear?
