My 03 Sequoia is running fine but oil is getting into the coolant and not the opposite. There is very little oil around the heater pipe that comes straight up from the back of the intake manifold and looks like oil seaping from the splitter junction just past that. Not getting any smoke out of the tailpipe or coolant in the oil but every time I drain the radiator full of Milky and dark brown liquid after I put green antifreeze

White smoke from exhaus and check engine ligh4lo and trac off
