and WOW! That was a lot of smoke that came out. Is a lot of that smoke just the color of the seafoam itself burning off, or was it really having that good of an effect? I ran it through the PRVR port on the side of the plenum, and it just shoved clouds and clouds of smoke out after starting it up again 5 minutes later. If it really cleared that much stuff out... then I advise everyone else to do this!
