So i have noticed the last month or so small oil drops under my car that smell like coolant. They are a little green in color so im pretty sure its oil and coolant mix. It doesnt do it every day though, like once a week.

Today was the first day that it looked green and smelled of coolant. I know i have a bad valve cover gasket on the drivers side, but i dont think its from that.

Any ideas where it might be coming from? It seems to drip from the bottom middle of the car.
