Will Sea Foam in oil stop lifter noise? [SOLVED]

Hi Anthony. The answer is yes if the lifter noise is being caused by sticky varnish. When added to oil, Sea Foam works to reliquefy harmful oil residues (like varnish) that can cause stickiness or oil flow problems. Just add half a can (most cars) every oil interval and pay attention to the noise. Though the noise typically fades away after one or two treatments, adding Sea Foam every interval will continue to clean and prevent oil residue problems in the future.
