The engine can indeed have external engine oil leaks - however, they tend to leak inward into the valley between the two cylinder banks. Then, the oil collects and runs out the back. It hypothetically could leak out the sides as well, as you have described, but much less likely. Have your rocker arm covers checked for leaks; do a leak test overall to verify any leak before deferring to a TSB that may or may not be valid for your car.
