I recently went through a couple oil leak fixes.
Firstly i was having oil dripping from under the front of the sump/harmonic balancer, but couldn't quite pick where. With the engine running the oil on the harmonic balancer would spray a nice line on the ground, due to the clockwise rotation obviously. I thought it would be crank seal, so pulled it apart and it surely was. The seal itself wasn't tooooo bad, but where it seats on the balancer, it had worn a groove into the balancer snout over time, and eventually leaked. If you are going to replace the seal, just be aware that you'll either need a sleeve that slips onto the balancer to make it smooth again(comes in most of the crank seal kits and a pain to fit) or, replace the balancer, which is what i did because it had definitely seen better days.
Seating the seal correctly is another issue, as it has to be centre. I can let you know how I did if you like, no leaks so far(6 months).
Anyway, after i put everything back together i stupidly didn't put a new half moon seal on the pan/timing cover. So it leaked from there, just under the balancer, and it only left a small pool of oil, never in a straight line pattern or on anything in the engine bay.
So basically if it is leaking from the front and leaving an east/west spray pattern on the ground when running or spraying your engine bay, it is definitely leaking into the balancer, which will 99% be your crank seal, unless it is a rarity like the timing cover gasket or so, but you should be able to visually see the leak if it was that.
