i need to know exactly where this hose connects to. i cannot find it for the life of me. and that the pic of my old block.. new motor is in the car.

 

pretty sure it goes to the drivers side of the iacv

 

runs to the IACV on the non-Z6
the Z6 runs to the pipe (the one that's physically connected to the valve cover breather) then to a nipple somewhere behind the thermostat housing.

you can trace the path...



**edit** on second thought, yours doesn't have the second nipple like the one in the service manual does. so maybe it does go to the IACV.
