A camshaft journal bearing was damaged due to oil starvation. after camshaft is replaced. Using a proper epoxy resin to fill in the damaged / pitted journal surface then honing the journal back to the standard size. After that adding groves or small pits that would work as oil pockets increase the chances of this journal bearing to work? I know most damage to the bearing is done during startup of engine, wouldn't having those groves or oil pockets protect the journal surface from contacting the camshaft and hence keeping it from getting damaged? any input would help, thank you!
