That smoke is nothing but the light aromatic oils from the MMO burning off ...it's not doing any substantial cleaning of note.
I thought the purpose of Seafoam was to clean the valves and combustion chamber, or is that not correct or did I misunderstand? I did see different colors of smoke: white mixed with black and a very slight smidge of blue. I believe the black was carbon? As the exhaust cleared, the engine sure ran better.
Perhaps I could be wrong, but after 29 years of owning the car, I have a pretty fair handle on how it runs so I don't think it was placebo.
