I have a 1989 LS Integra. I was looking under the car the other day and I noticed the PCV hose that comes fromt he PCV valve mounted in the intake manifold is simply hanging behind the intake manifold. DOes anyone know where it might plug into? It has a male end to it.

 

On my 92 RS, it plugs into the oil breather tank, that rectangular box under the intake manifold. I used a long screwdriver to press it in when I replaced the hose befor, it is a tight fit back there. Use a bright spot light and you will see the hole on top of the oil breather where it goes.

 

Is the oil breather tank near the oil filter? That is the nearest thing to the hose end. Hard to see what female end the hose would plug in to.

 

look to the right of the oil cap then up a little down in between the 2nd and 3rd runner on the intake mani. thats where it is on my DA.
