rust on cams

[bmw2101]

i have bought a set of cams and they have surface rust on t hem in places, it dosnt look like deep rust, but are they any good?

They are cat cams, so they are worth a bit!

1000 wet and dry them , i had a pair that got damp in storage and were covered but polished up nicely

thanks! Ill do that and see what happens, as i say its not that bad, but it is in brown patches. As said in storage in a damp place!!!

Hi, engine and drive train steel components are usually made of good quality steel which resist rust penetration lots better than mild steel. As said polish them up, they will be case hardened which is a few thou thick so you wont go through it.

Try a Brillopad as the steel they are made from will be softer than the hardened cam lobes so no chance of scratching.
