    3.8 water gushing from engine

    UPDATE: Installed an expanding rubber freeze/core plug successfully. Ran the motor on the lake with no leaks, engine temp steady at 150, and best of all NO WATER IN THE OIL. This leads me to believe that despite conflicting opinions all over the web, that the freeze plugs (at least on boats)...

    3.8 water gushing from engine

    3.8 water gushing from engine

    Found it. It's the plug. I think every single boat should have a non-removable tag in multiple places stating that it is REQUIRED for your boat that you winterize it and the procedure on how to do so. And also what will happen if you don't. So many newbies (including me) that had no idea.

    3.8 water gushing from engine

    1982 3.8 motor. When I hook up the muffs and run the motor, water starts gushing from somewhere under the lh side under the manifold around the engine mount. All the petcocks that I can find (4) are tightened. I have no visibility because of the fuel pump, engine mount, etc. Can't seem to...
