That is a big leak, wash the motor down (all over) with a big leak you should see it quickly, run motor and watch, as soon as you see any oil turn off so excess will not hamper identification of leak, big leaks can be from oil pressure switch, ill fitting valve cover gasket, front and rear crankshaft seals, cam seals, don't let it run for to long as the excess oil will make it hard to pick up the leak, don't exclude what you have done, either, as there still may be an issue there.
