If you see coolant dripping around hose #6 & 8, just change it. These hoses have a tendency to become brittle due to the direct connection to the engine block.
These are the picture of hose #6 and 8 remove from my car. See the broken part as compare to the new parts.
Also change the oil mist separator which changing the hose as it a major job to remove the air intake manifold, fuel rail etc etc.
