C2 cam wear

[Sean Carr]

I have JWT C2 cams in my car that I installed 4k miles
ago. This weekend I pulled the cover because I have
been getting some excessive startup clatter. What I
found was the intake cam looks like new, but the
exhaust cam has wear marks on every single lobe. Now I
am wondering if this cam was just made from a bad core
or what could cause this cam to wear so bad. Here are
some links to pics I took of the cam.
