So recently I have replaced my water pump, thermostat, hoses, thermostat housing and all the gaskets everything has been tightened even used gasket sealant on the gaskets. But yet I still have a coolant leak coming from the top and only reason I know it's at the top is there's coolant pooled up by the housing. I'm not sure what's causing it ibe replaced the thermostat housing gasket 3 times now and it still leaks.

 

Bypass hose between the pump, and the intake manifold.
