This hose splits off right before the return valve from the upper radiator





And here is the one mystery hose, and what should I connect to the valve cover too






Thanks!

 

the hose in the first pic goes to the thermostat housing, it should connect to the small fitting on the back or right side of the thermostat housing. the coolant hose in the top of the second pic goes to the small fitting exiting the inake manifold (looks like another hose is on there)
and the fitting on top of the valve cover is your breather, connect it to your intake, it should have a fitting too (your intake)
I just went out and looked at my motor, to double check too.

 

You are teh CHAMP FTW

Thanks !
