so the one that says manifold in the middle mine is setup where on the underneath in the very middle of the manifold I have one that comes out towards the front and one towards the back of the engine and the one in the front goes to one on the TB side still connected to the manifold. and then on the driver side of the manifold there a 2 on the underneath one in the front and one in the back the one in the front is closed off and then the one in the back of the driver side gos to the PCV. And then there are 2 little ones on the back side of the manifold that gos to EGR and to the resavore. This car ran fine with out a PCV in there before so I put a new gromet and PCV valve and new hose. When I disconnect the PCV and one of the other ones it runs better than when one is hooked up if both are hooked up then it wont even run won't even start without hold the throttle down? I'm getting really pissed off!!!!!
