So my boyfriend rebuilt his 93\\\' civic hatchback, but when he put the engine back it wouldnt hold any coolant, and it was leaking by the water pump, so we replaced the water pump-still leaking. He says that there is a valve that is right on the inside of the water pump on the block that blew, he tried sealing it but nothing will work (used jb weld)-and hes freaking out pretty bad-worried that the car will blow if he trys to take it to a mechanic

Im trying to find out the name of the part. It is no where in my haynes manual, it's a metal pipe coming from the thermostat housing to the water pump, the heating system in the car has been deleted also. Not sure if that helps, thanks

I'm sending a pic of a thermostat housing for that car if it is where pointer is pointing to he can go to a hardware store and buy a pipe plug and plug that instead of the pipe that is supposed to go in it.

It is the metal pipe that, from what I have read, comes from the oil cooler I think? Then goes into the block where the water pump bolts on but when you put a light in the missing water pump you can see it in the thermostat housing. I have an idea of perhaps removing the stock pipe, finding two fittings with threads on one end the other for a hose, then tap them out in the block and figure how to connect to the oil cooler the large black metal pipe in the picture
