Hope yall can help me on this one. I pulled my camshaft wanting to swap cams. after inspection i noticed the second journal back from the front has a pencil eraser size portion missing from it. It is a thin peice but nonetheless it is scored Is it ok to proceed with swap ? Can this be filled or smoothed over? Arent the cam bearings a little more forgiving> Please give me good news. Also if motor needs to be pulled does any body know a good fe mechanic in the greensboro nc area?
