Problem Description and Possible Solution
The heater hose outlet may leak coolant at the back of the intake manifold. Sometimes this is misdiagnosed as a leaking intake manifold gasket because it resembles a leaking manifold.

Car overheated, been hearing swishing water from heater core, coolant spilled over the road and water is leaking under passenger side behind the engine block, can't see exact source
I have the crack in the plastic part that the hose goes on. It is leaking and the guy at the station said I may have to replace the intake . That is a cheap way to make a car head intake for a car . I just found out the problem after a few weeks working on the hose and still leaking. I will try to fix it by melting the plastic back together with a solder gun .
