Yes Makg, and they are reporting that HHO corrodes the engine as well, wonder how long it will takes before the engine internal parts to break down from corrosion. Aluminum intake, Aluminum Heads, Pistons and a Aluminum Block. HHO is reported to also corrode other metals, so, Valves, spark plugs, Exhaust pipes and CAT.
I know you tried to pound this in my head earlier Makg, sorry for be bull headed.
