Cam Pitting

[gregwils]

I'm rebuilding a 160 motor and after considerable investment in lots of other parts, I now noticed more pitting than I recall on disassembly. There is plenty of it, but the pits are quite small and the pitting is restricted to the intake. The exhaust lobe shows very little signs of it. Attempts at cleaning it up with a light grit paper have yielded little.

I would prefer to have it cleaned up, but won't spend the money if I can safely get away with it. I'm in the US. Just in case, does anyone know of a cam regrinder in the states? Thanks.

Hmmm, I would probably use that and see how it goes. What do others think?

I would use that, too. The cam doesn't appear to be worn.
How many miles do you think might do annually?
Could take years to show any problem.

The worst that can happen is that the rockers may wear, but the opposite may be true - Maybe the pits will hold the oil and prevent wear?

I would just use that as is.......put some assembly lube on it before a start up.

Thanks for all the feedback. "As is" it is.
