Default Seafoam: smoke from engine bay normal?

I've done about 4 seafoam treatments over the years
This last one I got smoke from the engine bay
Is this normal (or vacuum / exhaust leak)?
Don't remember that before

Sounds like a vacuum or exhaust leak like you said. It's how I found an exhaust leak on my old beater!
