FYI
The December 2012 edition of the South African Vintage and Veteran Association magazine turned the spotlight on corrosion prevention in ally engine blocks and cylinder heads.
One interesting point stressed the importance of earthing these components on account of there being a small electrolytic current being in play due to the presence of cooling water and dissimilar metals. [Solution: put in earth straps and clean their contact points annually.]
Another article went into detail about the corrosion risks associated with high calcium levels in certain regions' tap water; a contingency that the author said is not satisfactorily ameliorated by the use of ostensible silver-bullet fixes in the form of branded water additives and anti-freezes. In his case, he made specific reference to his experience of working with Lancia engines. [Solution: Use distilled or rain water instead of the garden hose where calcium is present in the mains water supply.]
Finally there was strong support for a completely synthetic cooling and corrosion-stopping product that does away with water completely.
