This is an article by Marc Haibeck, owner of Haibeck Automotive the consumate expert on the C4 ZR1 and LT5 engine. He had noticed a pattern of head gasket failures where customers had used Dexcool in an engine designed for Ethylene Glycol, so he researched and published his results. Just some good reading as to why the gaskets fail thereafter. If our gaskets are composed with organic material, I would venture this would also apply to the GMC's Olds.
