Engine oil in radiator
Looks like I got traces of motor oil in my radiator. Yes it does have an oil cooler in the radiator. Any other way I could be getting engine oil in the radiator but no water in the oil?

Don't just look at the dipstick for water. You need to drain a little out of the oilpan into a clear container (big gulp cup) to get enough liquid to show them separating with the oil floating on top.
That oil cooler does seem like the likely culprit. Since the cooling system is under far more pressure than the oil system, if the leak were anywhere else, it would probably be water in the crankcase instead.
