I think its a coating inside that flakes off the magnesium valve cover. I think they put the coating on to protect it but the heat cycles makes it fall off. I am not sure if blasting and re coating it is the best idea, or if just blasting it clean and adding a new gasket would work. I am just leaning towards replacing as the time it will take to clean it up then recoat is going to cost me close to just replacing.
