I am in the process of doing a b16a swap into a 89 crx si. There is a connection on the back of the motor that is capped off. I am wondering what is supposed to connect to this? The connecton is located right below the head between the first and second intake manifold runners. Any help would be appreciated.

 

crankcase ventilation?

 

does that attatch to the intake manifold?

 

heres a picture of the connection im talking about

 

On my A6 there is a coolant line there.

 

I believe thats the one that goes to the breather chamber
