just finished new head gasket job on my 99 civic dx. it runs fine but on my first test drive i noticed coolant leaking from the small steel barb on the back left side of the intake manifold. i must of bumped it when doing the head and it was a little rusted. now its leaking, it looks to feed coolant to the idle air control valve.
how can i fix this? can i somehow fix the steel barb or do i have to buy a new intake? this is a steel 3/4inch barb with a smaller 1/4 barb coming of it that leaking. it looks to be pressed into the aluminum intake.

do i even need warm coolant running to the iacv? can i seal it off some how.thanks

 

The IACV controls your idle, so yes, you do need it. No, you can't seal it off if you expect the motor to run correctly. Yes, you do need to replace the intake manifold.
