i watched the video and agree with everyone above ^^^
the smoke is blue because your burning oil and it could be a couple of things, you won't know for sure until you do the above.
I wasn't able to see what bov your running but my 1g bov made the same whistle at 3-4 lbs of vacuum, i could get it to whistle on command even being recirc'd.
there might not be anything wrong with your motor, you might just need a new valve cover gasket. hopefully everything checks good man...
