TREX87

Replaced the cam this weekend and after reassembly--put fluid in the radiator, it all came pouring out of the water pump. Took it all apart, tried it again, same problem. Got a new water pump, same problem! I'm not talking about water coming out of the weep wholes behind the timing cover (though water does come out there); I'm saying it leaks like it's not bolted. Bolts met torque specs, new gaskets, tons of sealant. Chances that the timing cover is cracked, warped etc. seems far fetched. What gives?
