can anyone directed me to a site showing this? having a troublesome leak on the water pipe behind the motor, up near the head, thanks

 

why this question? I have been battling a small coolant leak for a while.. one end of the pipe behind the head go's to the turbo coolant passageway, the other side behind the head just to the right of the timing gear,, a short hose, about 3"long, just above the hose from the coolant tank.
