I recently changed my water pump on my 390, and that was one hell of a b!tch, every bolt decided to break at the head. After i drilled and taped every thing and put the water pump on, i thought the water neck would be the easy part. But for some reason i keep crushing the o-ring and the damn thing leaks. Is there a trick to this or is it just my bad luck. The guy at napa told me to pull out the o-ring a just run some rtv but the scares me. Any help would be great. Thanks!
In an emergency, and this sounds like one, you can cut a gasket from a CornFlakes box, grease it up and it'll work for a good long while. O-rings on thermostat housings/water necks ****. Gaskets work.
on the cad you have a water neck housing gasket witch is working fine for me but down below the thermostat theres a nother o ring that goes into the water pump and thats the one thats leaking. i'll get some pics up.
Did you get it to work yet?? If not, my friend fixed mine and for the life of me I can't recall how he did, but I will ask him and reply to your thread A.S.A.P.
I've done a few of these water pumps on '60-'64 Cadillac. Usually the neck that the O-ring fit's over is pitted to hell (making a bad seal). What I use is a lot of "The Right Stuff" sealer all over the O-ring and joining part. Never had a leak. Good luck!
this problem is for 63 and up only guys. you have to finesse it in there. some guys run 2 o'rings. ive never had luck with that , so i usually run some sealer, on the oring as a lube and pack the oring into the housing, pump housing, first and then slide the cross tube into it, you can of need to **** it alittle to get it to clear the heads. i just used ****,head,and lube all in one post with no ***ual reference.
