Soaking time and Sea Foam [SOLVED]

Hi Robert. There are 3 common approaches to consider when it comes to Sea Foam applications and soaking. 1. Soaking dirty engine parts (after removal) in Sea Foam is obvious. 2) Long soak times (overnight, several days…) are helpful when adding high concentrations of Sea Foam to fuel to overcome carburetor and injector restrictions (gum, varnish, carbon. 3) When it comes to upper engine cleaning (Sea Foam Spray through the throttle body and other intake applications), it’s best to limit the soak for 15 minutes or so because engine heat is important (hot soaking). Letting the engine cool down can cause plugs to foul, requiring removal (a pain). Anyway, a shorter hot soak time (not letting the engine cool down after an intake cleaning) works better than a long soak (overnight). I hope this makes sense!
