I'm a newb on catch cans and I just installed one because I had the pcv hose and the valve cover hose disconnected so I thought mind as well just add a catch can. As soon as I installed the can I got this whistling noise during start up for about 3-4 minutes. When the engine warms up, it goes away. (b18c1)I have the vacuum connected to one of the vaccum lines and the other side connected to the valve cover and T'd to the pcv. It's getting embarrasing to drive away from places now since It appears like I whistling at people when I'm driving by them. Please Help!!!!

 

anyone?
