I may be saying this completley wrong, but from what I've read on various articles and from service technicians, DEXcool is not reponsible for eating gaskets necessarily. I believe it'* more of an engineering problem than anything else. If DEXcool were so responsible for eating gaskets, wouldn't the 3800'* with DEXcool be having blown head gaskets as well? How about all the other gaskets? I believe that if the DEXCOOL is flushed at the same interval as the green traditional coolant, there wouldnt' be so many cooling problems with sludge. What would happen if you ran the green stuff for five years? Sludge? exactly. One source I found at one point actually said that the green stuff was more prone to eating things like the water pump. I don't recall seeing many 3800'* with DEXcool having waterpump failures like the models with the green coolant. Just my observations.

it is a recombination of gasket material and dexcool'* natural corrosive nature, some gasket materials are less susceptible to the corrosion than others
