coolant on-top of the intake manifold
Hey guys i have a 1985 rx7 GSL 12A with a few mods. im starting to see coolant on-top of my intake manifold i have a Holley 4barrel carb and manifold. i only see it when the car sits for a whole night or a more then 4 hours and its not very much coolant i see there. i have ideas on what it might be but i would like a better opinion i think it might be my intake manifold gasket. other people are telling me it could be the overflow tank but i don't see how that could cause it to leak on-top of the manifold. any help would be very helpful.

There are two o-rings that seal the intake manifold to the water ports on the rotor housings. These allow water to run through the intake manifold and keep it warm. They are likely leaking.
There are also some coolant hoses in that area as well, like the heater hose that crosses over the engine. Make sure it isn't leaking.

i checked the hose that runs above it and its fine and doesn't leak. anyway to fix it without having to change the gasket for the moment at least?
