I just bought a 91 integra with a B18 motor. It neede a PCV valve so I got that but I am not sure wher the vacume line runs to. Does anyone now where the line from the PCV valve goes to and what it connects to. Thanks.

 

its in between the runners or the intake manifold, follow the hose from the center of the manifold

 

On my 92 RS, a hose comes from the intake manifold to the top of the PCV valve which sits inbetween the runners, and another hose goes from the bottom of the valve/runner to the oil breather tank on the backside of the block.
