Will seafoam quiet a lifter

Seafoam is often used as a cleaning agent for engine components, including lifters, but it may not always quiet a noisy lifter. It can help dissolve sludge and deposits that might be causing the lifter to stick or function improperly, potentially reducing noise. However, if the lifter is damaged or worn, Seafoam may not resolve the issue, and more extensive repairs or replacements might be necessary. Always consult a mechanic for persistent lifter noise.
