F22A leak/ problem

[AccordTNR1219]

What up all!
Recently my 93 honda accord started leaking oil profrucely. I was on my was to school when some thing broke. I had arived at school when i found a trail of oil and i large puddle that had acquired after only a couple min. I drove home which was only a few blocks away and with in 3 min of getting home all of the oil had draind out. It all seems to be seaping from the Timing belt area. Does any one know what might be causing the leak and why so badly? Also if what it would cost to repare the problem by means of me and or by a mechanic?
