340 water neck leak.

I had that problem, and it about wore me out. Must have taken apart and put new gasket and sealant on it a half dozen times.

Turned out that the aluminum intake (LD340) had the bolt holes for the thermostat housing, all the way through to water. The water was leaking back up around the threads.

I put studs in it, with thread sealant (silicone will work also) then the problem was solved. Mine is dryer than a bone now.

I agree, with the chrome water outlets, you couldn't give me one.
