Hey Army,
I didn't post any info on the cleaning as I rested on the shoulders of giants. There are a few threads on the topic which degenerated into a dispute and argument over how the process works. The gist is that the water "steams" away the junk. That is my summary so for all those who are much more scientific please excuse in advance. There was an example by a forum member who pointed out that if one blows a head gasket, the internals become very clean because of the water / steam created by the head gasket failure. I know from the STD community that the water or W&M injection, the vapor lowers Exhaust Gas Temps. And, the "M" gives an added kick or boost so to speak. I will be burning W&M in my turbo engine to lower the temps and for that added boost. However, for this application, no need for the boost. Only so much mojo out of a tired 77 HP engine. Hope that helps ...
