WHERE IS THE MOST COMMEN PLACE FOR A OIL LEAK TO OCCURS?

Oil pan gasket or broken pan & head Valve gasket i would also check the oil pan screw maybe is loose.

hello , on tjhis vehichle it is very common for the oil pump housing to leak ,, it is located in the front of the engine , and is run off of the timing belt ,, go to the parts store and ask for some oil dye , most of them will have it , add it to the oil and let the car run , you will be able to see where it is coming from ,, no problem ,, if it is coming from the lower timing belt cover area then bet on a oil pump housing gasket
