I went to check my oil and noticed a white, milky substance on my dip stick. I imagine its my radiator fluid mixing with my oil. Am I correct? I've been told by other ppl that the cylinder head in cracked or my head gasket is busted. In this economy I can't afford to take it to a shop so I would much rather do the work myself if possible. I've gotten most of the engine taken apart to to take the head off but I'm stuck after taking the valve cover off. I need help. Any tips or anything on helping me get the rest apart?
