I agree with it might be the Thermo slid and it crushed outside the groove on the housing, If you take it out add a little gasket sealer and then put a new gasket on , let it sit for 15mins or so to let it set-up then install it. If it is leaking out the weep holes on the pump the water pump is bad, I would suggest a Stewart Componets high flow pump it works great for me. $69.00 non-polished $89.00 polished.
