6.0 in my 2000 trans am

[stoney0803]

okay this is my first post to this site and i am in need of some help. I have just finished up installing a 6.0 out of a 2007 suburban into my 2000 trans am. My problem starts here I dont know what to do with the pvc system we had the car running today and i pulled the oil fill cap off and when i did i heard a suction noise come from the oil filler tube. We currently have a breather on the tube on the back of the driver side valve cover and the tube on the passenger side valve cover hooked up to the vacuum port on the intake. was wondering if anyone else has had this problem and if so what you did to fix it. thanks

look at using a ls6 valley cover tray and then into a catch can?

Also did you plug the pass side rear port? It has 2 of them.
