could methanol cause engine damage?

[megafreakindeth]

a guy with a dodge cummings(running 12s) had water injection that he home made. i asked him what mixture he was running and he said only water, methanol leaves deposits if you use it frequently. the trick, he said, was to wash it out with pure water injection every now and then.

methanol destroys most fuel lines(whch i thin are nylon) whch is why the less efficient ethanol is mixed into your gas at the pump.
