so i put a brand new water pump on my new 383 i get. and have to pop off the rear cover to compress the pump so the pulley lines up nice with the crank pulley. put the cover back on. now about 2 months later i get the truck running and the cover leaks. i think nothing of it and just get all new gaskets to redo this job and be over with it! that doesnt happen and i get it running after taking a long time and doing a nice job and it leaks again! even worse! i guess this is just a part of working on old stuff. its a blast to work on though.

Chances are you busted the shaft seal pressing on it and are going to need another new pump. When I did my friends 350 last month he put a fluid damper on it we had to make up a shim for the pulley on the water pump, to move it out .060 to get the pulleys to line up.

NOOO more bad news! haha dont tell me this!, i bet we did break that seal to now that i think of it. would that make the antifreeze like wanna come out really fast and you can actualyl hear it sizzling away ? thanks

actually breaking that seal, wouldnt it come out the front side? mine comes out the backing plate there. i think im going to try one more time with all new gaskets and a lot of that rv stuff, and let it set up over night. if that doenst work then ill have to fork out some more $$$$ for a new pump. thanks guys
