What is the best way to clean carbon from the valves and heads of a 911 engine?
Thanks, Bob |

Yep, done that. It's kinda' fun. When I was working as a "test fuel additive rater" in the Test Fuels Additive Lab at Chevron for a couple of years, I learned that the quickest "clean up" additives were the ones with the highest percentages of Techron/Techroline. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) There was a point of diminishing returns. Yes we did test other competitors additives but there was only one better than techron at that time. Amoco "Clear" was #1 back then. Only sold back east. Shifting gears.......... Glass beads are great as long as they are COMPLETELY removed from the heads once blasted. They have the potential of being very nasty if there are residual beads. The "One bottle and pass" stuff does work. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) My old '72 Chevelle appreciated it and so did I.
