Typical of the 2.5L. Remember two things affect your leak while it is running, gravity and the airflow in the engine bay while running from the fan and driving forward. So maybe it just finally has the ability to run onto the floor when it is off.
Typical leaks are valve cover,dipstick, distributor, ooil pressure switch (sending unit) by the distributor and finally the rear main but not so much on the 2.5L.
It is probably running down the right side of the block and gets all over the starter and then drips from the bottom of the bell housing.
