I hooked up the pvc and the tube that comes off the right side valve cover to the inlet before the supercharger. I had the same problem at first, it caused a oil leak.

This is kinda important to do. On top of this, I threw out the PCV vavle which was not functioning sufficiently causing my oil to shoot out from my dipstick when I hit heavy boost. I put in a bigger Moroso oil separator instead of my new PCV valve.

Doing this will give you some vacuum to help the rings seal better and because of that will make your engine produce some extra horses. Also this will reduce blowby as well.

Finally the breather will not give any vacuum but may also allow foul smell to get into your cockpit.

Some people I believe are doing just the breather and is working ok. I won't do this unless I have to.

Now I know why my intake started leaking with less than 10miles on the new motor. the lifter valley must be pressurizing under boost via the passenger side valve cover.
