Its been a minute since my original post but I took a common sense approach and pulled the plug. Nice and tan. No signs of oil blow by from the rings and the engine has been running the same as the day I picked it up. So I can rule that out. Looked a little closer and it appears to be a very small leak at the bypass elbow. Many have speculated here that may be the case of the water being cooked out of the antifreeze leaving a oil-ish residue. Sure looked like oil but indeed was coolant. Thanks everyone.
