There is a weird wissling sound from the engine, no smoke or anything it is just the sound. When I shut the breather close for 2 seconds, the sound will disappear for 5 seconds and it is back again???
Any idea guys?
Thanks.

No affect on idle and I don't think there is a vacuum leak because I have a boost gauge and it reads vacuum @ 21

its just the sound of the air rushing through the hole... run a line from it to a catch can, thats the best thing to do... or just run a hose from it pointing down at the ground around oil pan level.

I got a question for you alghafat424. Are you running any vacuum on the pcv system, or just an open breather? If you are running no vacuum, what kind of gas mileage are you getting, because I heard it will go down if you run with no vacuum on the pcv system.
