Cam lobe damage

I think this roller cam is usable with a slight soft cleanup. It's the only damage and the rest of the lobe looks perfect. What do you guys think ? Is it usable? How would you go about cleaning it up ?

Truth stands on its own merit.

Nope, need to send it back to mfg for regrind, or shelve it. It will only get worse, and take out the next lifter you put on it very quickly. When a roller lifter lets go, bad things happen all over the bottom end. BTDT. Joe-JDC

Looks too deep to scuff. What happened?

A roller axle failed and came partially out of a comp cams roller lifter. I have also had comp cams full skirt lifters crack or break, lucky not in a critical place but it's never good having pieces laying around in the engine. I switched to crane lifters about 5 years ago that only has the partial skirt were the link bar goes and haven't had a problem since. I have never ran the morel lifters before but most of the guys here seem to use them so that will be my next set.

Thanks Joe. I was hoping to make a couple bucks, I'll pass the info on to the prospective buyer though. Maybe I can make a mailbox post out of it.. oh well.

I wonder if the cracked cam thrust plate was caused when the lifter went astray, jamming the cam's nose into the plate. Agree that that lobe needs manufacturer help in a big way.
