Coolant leak again

After a long ride, parked my 89Civic on the driveway. A whole slew of engine coolant squirts out on the driveway. Its squirting from the engine behind where the first spark plug is on the left (facing car). Afraid could so much coolant leak out as a result of the fluid going into the engine and damaging the intake manifold ????? There is no particular smoke color coming from exhaust, and smoke looks healthy.

Saw the fluid squirting out from a small hole in the 1 cm diameter rubber pipe that connects to the back where the 1st spark plug is, and goes down and connects "somewhere". Could this pipe be connecting to the intake manifold?

That line is what either feeds coolant to the number four cylinder wall, or is a coolant line for the fast idle valve. Either one passes through the intake manifold flange. Should be a $15 part from honda.

THANKS Kris.
