On the gsr manifold there is an "L" shaped fitting on the rear upper right side, it points upwards. I pulled out whatever went connected to that along with some other stuff. I am putting everything back together & I cant find the connection for it. Can anybody tell me exactly where the hose that goes to that is.?......Also I turned my motor on after installing the rear motor mount & it revs to 3k & stays there. Could this be because that fitting on the manifold is not connected, if not what might cause this. Im guessing something is unplugged. Thanx

 

sounds like your vac. lines got mixxed up wich is easy to do....also sounds like you need the PCV line for that one fitting...not positive though but its a try

 

if you have a hole in your manifold, its gonna rev high.
