Next time you are near a Cat dealer stop in and ask for their booklet on sour coolant and cavitation holes in the cylinder liners of diesel engines. Antifreeze breaks down to sulpheric acid from heat and air. that is why the proper ammount of additive (dca 4 etc) keep's the coolant slightly alkaline to neturalize the acid.Your theory of iron parts developing a rust layer that when it gets thick enough will choke out further rusting does not work on a diesel. The constant detonation shock in a diesel's cylinders will make the sleeve's ring like a bell which will flake off the rust layer which exposes new bare iron. If the antifreeze is sour(acid)the rust will quickly form again. After a few thousand of these rust then flake cycles the rust goes completly through the cylinder wall. Because of the design and mounting of the sleeve the ringing effect concentrates itself on certain areas which are where the sleeve pits form.
Another problem with sour antifreeze is that sulferic acid will eat up the tin content in solder(60% lead-40% tin, sometimes 50-50) lead is not affected by acid but tin is.After enough years of old acid coolant your radiator is now held togeather with low strength lead swiss cheese instead of solder.
Check this out at a diesel engine place. Their agenda is not to sell antifreeze, but to have that engine run a million miles so you will come back and buy another one.
