Hey guys, lookin for a lil insight, i've got some coolant & vacume leaks on my swap. So this might be an on-going thread for a lil while.

The top radiator hoes goes into the port on the head.. but on my head there is a a smaller (looks like 5/16th maybe) port that comes out of the upper radiator port, pointing back twords the firewall at a downward agnle. where exaxtly is that supposed to be routed to?

if a picture is needed i can provide one later on tonight.
