water neck/inlet leaking???

  • Hello, I am battling a leak on my water neck housing. I have replaced the gasket several times with the same results. The leak is on the bottom portion of the water neck and the water/coolant pools in the valleys of the front timing cover. No leak from the timing cover. Any suggestions? The surfaces of the intake and water neck appear to be fine, no waves or anything. I am going to buy a new water neck and try this next, but would like to get some input before I start. Thanks.

  • Have you put a straight edge across the mating surface of the intake and the surface of the neck? One or both of the two may not be perfectly flat. Also, hopefully you're not using a chrome water neck. They always seem to leak.

  • we just discovered that ours leaked too!

    i had filled up with antifreeze

    and here it came dripping out the bottom bolt hole also!!<img src=images/icon_smile_dissapprove.gif border=0 align=middle>

    we took it off

    cleaned the surfaces (some pitting)

    used the straight edge check

    new gasket and liberal black silicone

    and let dry overnight

    will see today if it leaks

    hopefully not as we don't want to replace

    the aluminum 'edelbrock' intake manifold'

    will let you know what happens

  • In my humble opinion the chrome water necks are crap.

    Mine leaked as well and it didn't stop until I replaced

    it with an original. Also make sure the thermostate fits

    into the recessed area on water neck or in the intake.

    That falls in the catagory of "oops, damn", if you tighten the water outlet with the edge of the thermostat in the way.

    well, it's not a hipo

    so will just get a new one

    for about $45!

  • it turns out

    that it was probably overflow

    out of the radiator.

    our rubber tube only extends

    down to the upper level of the frame

    and we had filled the radiator to the cap!

    it doesn't leak now
