So, I changed my oil two days ago and I noticed that it had a little water in it. I didnt think much about it because I figured it might have got in my engine when I was washing it or something. Well, I went riding yesterday and just happened to check my coolant level and noticed I had oil in my coolant. There was enough in there to make my coolant have foam on the top and it was almost black. After seeing this I am assuming that the water in my oil was not from washing it or riding through water. Does anybody know where these two fluids can mix in the engine? I need some sort of a diagram of the head or the block. Any info is greatly appreciated.
