coolant leak

i have a leak that is coming from somewhere near the thermostat housing i took it apart and re made all the seals with the right kind of sealer and it still leaks
could it be the water pump itself that is finished or just th thermostat housing plastic part?
it leaks enough that i have to add prestone every day or two
has anyone had similar problems or fixed something like this some info would be very help full
thanx

Hmmm...

I do know that if you see coolant near that little hole in the bottom of your waterpump, your waterpump is finished. This may or may not help you.

Good luck.

P.S.
RMR has good deals on OEM pumps. (VAG might too)
