cobraman 484 Can you shoot a couple of pictures to see what they look like? You didn't say what the valve lash was on your motor? Poor oiling system is what kills these lifters. If not pressure oiled they will not last long. I even question the
oil pressure ones. Ilding kills these lifters faster then anything. You may want to talk to your machinest and ask about a spray kit that will put
oil right on the cam and rollerwheel. If the lash is too larger you are pounding the wheel out on the cam and causing the same problem. Do you have a preoiler like a accump 3 qt. before you start the motor. I think if you read or talk to any of the lifter tech people they will say to make sure you don't drystart the motor. I know Jessel does. Excaliber had too much valve lash and broke a shaft in his motor. Yours is not the same thing. Rick Lake
