Will Sea Foam in fuel clean a dirty EGR valve? [SOLVED] Asked by Tanner D. In Louisiana Will Sea Foam work to clean a dirty EGR valve?
Thanks for the question, Tanner. Adding Sea Foam to fuel will not work to clean a dirty EGR (exhaust gas recirculation) valve. Cleaning a dirty EGR requires removal to clean or replacement. For removal and manual cleaning, Sea Foam Spray works excellent for spray and soaking dirty EGR parts!
