Engine oil turned milky, which of course means engine cooling water is mixing with oil. Obviously the head gasket is gone pushing oil into the cooling system. I went to NAPA, for $40.00 bucks on the advice of a guy behind the counter said give a head gasket sealer a try. So, what the hell. I forked over two twenties, dumped the stuff in (not even cleaning out the milky scum in the expansion tank) and - hey, its been working for over a year now.
