What about using Sea Foam through a vacuum line? [SOLVED]

I’ve seen videos and heard stories of people adding Sea Foam through the brake vacuum with both good and bad results. Just wanted to get your thoughts on it straight from the horse’s mouth, so to speak.

Great question, Stephen. That’s an easy one! Never add a fluid (including Sea Foam) to a vacuum line. It doesn’t work very well, and because a piston can’t compress fluid, can hydro-lock and ruin an engine. Sea Foam Spray works much better and safer! It also feeds all cylinders evenly. Hope this helps!
