Now you do Spernkey! The H2AD did suffer from spalling under certain circumstances, mainly under use. The 'T' mod, using the correct oil/additive and regular use is the answer to the H2AD 'problems'.
My engine has had the 'T' mod from new, has always used the correct oil/additive and is used regularly. The oil analysis', corrosion checks and compression checks are always very good and it runs sweet as a nut. I have corresponded with a number of other H2AD owners and I hear the same things from them.
Thanks for the warning though, it's good to know you worry about my health
