Seafoam

Has anyone tried to seafoam their 2001 sienna. It is almost impossible to reach your hands to the brake booster to get the vacuum line. Theres just too many things in the way. Just wondering if anyone else has tried and succeeded.

Yeah, this post is over three years old, but it's still an unanswered question and one many likely have asked themselves. The answer to your question is... you don't go through the brake boost line in this situation. Instead GO THROUGH THE PCV VALVE VACUUM LINE. That will get it into your intake.

I recently saw a video posted on another automotive forum about how to do this. In the video I believe that he used a vac line that was on the TB.

I've only used it through the fuel tank of my '01 Sienna. MPGs went from 22 before to 24 after.
