Oil dumped out everywhere

Ok here is what happened went to church this morning everything was fine didn't speed today. Get back in my car 2 hrs later and stop for gas, when i get out i see a trail of oil drops about 10 ft back leading to my car. I check the dipstick and sure enough it was WAY below the marks so i dump in a qt and start up the car and look under the driver front wheel and it's leaking MAJOR right by the crank pulley!! :( So here is what has been done in the last 2 months. put on new water pump and ALL new belts and also replaced the oil pump O-ring and the filter base o-ring. The only thing i can think of is maybe the oil pump o-ring blew again or the front seal on the crank but it hasn't had anymore oil than between the marks on the dipstick. So any ideas? And how much am i looking at??? Or does and can the oil pump go out and cause this maybe? 92 accord wagon 140k
