2002 ford focus se is making a motorcycle noise from under the hood. I found the problem but cant find a name for the part. It is and aluminum pipe bolted to the manifold and goes to the dash (well connects to a part by the dash). Anyways where the pipe is bolted on the manifold is where my problem lies. The pipe is no longer connected to the bolted piece like is should be. I just need a name for my part please help!
