Hi,
I have a '74 Omega which I recently changed the heads on (to '71 #7 heads). I also changed the stock EGR intake to an Edelbrock Performer. I noticed that the original intake has a valve of some sort on the water exit port going to the heater core. Ever since changing the heads & intake, first my original heater core let go (blew up, really), then I replaced it (man, that was a lot of work!), but it too is leaking. The only thing I can think is causing it is not reusing (or replacing) that valve coming off the head going into the core.
However, I've noticed that earlier years/ models of not only Olds, but other GMs didn't use that valve. Has anyone had an experience like mine with changing the intake and having their heater core blow up? Any suggestions?
Thanks,
