Noisey Lifter

An update. Removed valve cover, removed lifter. Lifter mating surfaçe to cam lobe looked good, cam lobe looked good. Removed distributor and spun oil pump. Lifter cylinder was receiving oil. Broke down and bought another lifter. Installed and put everything back together crossed my fingers and started her up. Lifter pumped up and quiet. I am chalking it up to a bad new lifter. Really getting tired of Chinese junk. Thanks to all for your suggestions and input.
