Ok now here is the problem:
ok first is it possible to have a blown headgasket and not notice any powerloss? second if i drive my car normal it doesnt overheat unless i drive for like 1 or 2 hours but if i drive say around the block and drive it hard when i get bac in the driveway i can see the drips of water, then i look under the car and water is leaking where the overflow is. but like i said i havent noticed any powerloss. so can anyone help me with this.

 

possibly a slow leaking head gasket,but a leak down test should help even more good luck
