This problem with aluminum is something I have been wondering about.  Does
this apply to the intake manifold, the cylinder head, and what about the
pistons?  I haven't been able to find much information on the corrosive
properties of ethanol versus pressure and concentration on aluminum. 
Anyone have some links?

Thanks Morey.
