Oil could be valve cover gaskets or distributor seal.
Anti freeze could be any number of things.
Water pump or gasket, freeze plugs, intake gasket, leaky radiator splashing back on the engine.
Clean up the engine as best you can and watch, use a backlight you have it, oil lights up under a black light.
If the engine isn't too hot, run your fingers along the lower edge of the valve covers, might get an early sign of a leak. Antifreeze should light up some too under the black light.
