Can I wet sand a cam beaing? The end cam bearing has a small knick and I can feel it with my finger. I was wondering if I can wet sand the knick on the cam bearing smooth?

id just assume replace it...if you were to do this i wouldnt do it with anything less than 3000 grit...

Just go over it with a gray Scotch-Brite pad. Every time I get an engine back from the machine shop, I do this because they always install a cam dry to make sure it spins freely after they put new cam bearing in.... and they always seem nick the bearings up just a little. It's not the end of the world if the cam bearings are nicked a little... they are very soft and almost always a gray Scotch-Brite pad will smooth them out. Just don't get too aggresive and clean them very well to remove any left over grit or bad things can happen.

no sand paper on bearing surface

Why? Not even wet sand paper?

I have steel wool, can I use that? Or is that to rough to use? And where can I buy grey Scotch Brite pads at? I was at Home Depot and Lowes and they do not have them.

Try an industrial supply store......

I am an old school Machinist where we used to scrape our own babbit bearings. Tolerances are so close you have to be carefull. Sandpaper will not help. Take a jewelers file and carefully hit the high spot and then lightly touch up with crocus cloth to polish the area. Crocus cloth is what we use to polish bearing diameters, journals, you can find it at Graingers or other machine shop supply.. I always keep a roll handy.

you don't want fine grit embeded in the surface that the naked eye can't see

He hit the nail on the head. Also, do not use water on crocus cloth, just use it dry. It does not leave grit obviously. Make sure you wipe with soft cloth between procedures.
