I started investigating and first thing I did was drain the coolant. It looked as clean as when I poured it in, since the oil is less dense than the coolant it would make sense that the oil would go to the top of the fluid in the system located in the expansion tank. So it may just have a small leak? somewhere? I haven't yet removed the heat exchanger, but its next on my to do list. That's how limited my time is I can get one thing done everyday before work, all the help is much appreciated
