Question on new HotCams

Recommended Posts

I just received my HotCams and noticed the lobs on the cams are not machine polished like the part that meets the cam journals. The lobs look like they are black oxide.

Is this normal? I've never seen new cams before, only worn ones.

TIA

Erik

The lobes on your camshaft are likely "Parkerized", a phosphate based conversion coating that helps hold lubrication on the cam surface during break in.
