I was getting ready to clean up and reinstall my rocker arms and found 6 rockers with similar failures as pictured. They basically failed at every other arm except for the last four on one side. In all cases failure occurred at the spring spacer, not at the washers. Is it worth replacing the bearings and trying to use them again? Any thought on what the cause of failure may be? It's strange that the bearing retainer would push out like that is it not? Let me know what you guys think. Thanks, Trent
