i just used pure water from gas stations..
how much will i spend if i have to fix(typicla value)
1. cylinder gasket
2. radiator overhaul
3. typical labor
4. leaks(in relation to this, i saw some oil leaks dripping from my hood but not much..does it has something to do with this?is my engine problematic?my uncle says my enginer is in tip top condition but why the drip?it is dripped somewhere from the left part of the hood..not much though...just bits of driplets..

thanks again!
