Re: Oil leak?!
Wow, leaking pretty good!
As mentioned earlier, that is your water pump and pretty sure it is just the oil seal leaking.
The pump drive shaft has two seals, one on the water (outboard) side and one on the oil (inboard side). There is an air space with a drain hole between them. If you look behind and under the pump you will see the small (about 1/8") drain hole. If the oil is coming from that hole you just need a seal. If it coming out just inboard of that, it is probably the water pump housing o-ring. The seal is a more common source, the o-ring rarely is a problem.
Do a search for water pump seal and you will get lots of threads, etc.
Changing the seal is harder (but less expensive) then changing the whole pump. It depends how handy you are.
