You sure about the amount of oil lost and at the mileage posted? How many miles on your Accord? Rethink the question, it just don't add up on a Honda! Wait awhile, maybe the Honda Tech. here can be more help.
Check the very bottom of the timing cover for any oil droplets, if front balance shaft seal came out , it will leak oil down there but most of it will blow back while driving and not leave a puddle under the car when shut off.
