I usually remove the oil filler cap and feel to see if there's excessive pressure (blowby) from the crankcase. Should be very little if any on a good engine.

If you haven't found the oil leak already, as Ocampo Dave mentioned, wash the engine really good. Oil tends to travel and sometime difficult to find. When looking for hard to find leaks I buy a couple of cans of degreaser and pressure wash the engine really well. Then I use a mechanic's mirror and a flashlight for hard to see places.

I've had leaks on the rear of the valve cover and the rear intake gasket and oozing out of the oil sending fitting on the engine. The most common ones are of course oil pan and valve cover gaskets. Also, the rear main seal and front timing chain cover.
