Depends on where it is leaking from,ive seem many of the older models leak out of the upper hose going to the engine block it will have green residue.Water pumps dint need to be changed often, normally you would replace the pump when doing your timing belt since the pump is ran off the timing belt.Valve cover gasket will just seap oil,and thermostat will either stay open or stuck closed,closed will cause to overheat.since you see fluid best bet is to do a visual check to see if you can spot where its coming from, if not take it to a shop.They will pressure test it and see where this leak is coming from.
Also with your Valve gasket, accords have a extended emissions warranty up to 150k miles that will replace your plugs,wires and cap under warranty these are common to have oil in the spark plug holes,but honda will basically give you a free tune up if it has yet been preformed, all you have to purchase the replacement for the spark plug gaskets and valve cover seal.Hope that helps.gl
