ok b18b is in
on that second pic a hose doesn't go there it is the place you open up to burp your cooling system. The one on top of the Intake manifold goes to the canister down below your battery. I think that this is what you are asking right?
i dont know anyone with an integra. I got my car to back fire, so it is getting closer to time. I have figured That I dont have it on time. Anyhow the front water neck doesnt have a nipple to blead the cooling system. That spout comming out of the neck constantly puts out radiator fluid. ahh this is a pain in the ass.
That line probably goes to your throttle body.
I HOPE you have a service manual for the car this engine came out of. All of your answers are in there. There will be vacuum diagrams, and coolant diagrams that will sort out all your hose problems. You don't want coolant going into ANY vacuum line, and there are both coolant and vacuum lines connected all around the intake manifold.
You'll find coolant lines on teh throttle body, AICV, oil cooler (if equipped), heater core, and overflow bottle. Vacuum lines on the throttle body, intake manifold, emissions equipment, valve cover, brake booster, and sensors. Water entering any of those parts would be horrible. Whether it's a water or vac line, it's imperative for it all to flow right in order for the systems plugged into them to work properly.
