the throttle body is capped off like i previously said. The car is in speed density anyways so it wouldnt make much difference. running a catch can takes up too much room, i hate the way they look. I change my oil constantly anyways so im not too concerned about not having a PCV system.

I would be curious to see if this problem still existed with your car, after you ran a vacuum line from the LS6 valley cover to the TB/intake...

He said German Castrol earlier. It's the German blend of Castrol Syntec.

I capped off the PCV but REALLY liked the positive suction/ventilation i had previously from the tube coming from the manifold into the pass valve cover...SO, not only do I run a breather, but I also run a catch can from that valve cover to the manifold...I got rid of the ugly PCV but still have the positive ventilation..AND no oil in the manifold...NICE

Wouldnt running a breather and a catch can create a vacum leak?

yes it does to a point, but not enough that it is going to affect performance or anything....
its probably more preference/appearance for me, as I stated in my post above...however, the way I have it set up, it still serves a purpose and still creates a POSITIVE vantilation, instead of just venting through the breather naturally..

ALSO

it keeps oil from coming out of the breather...before without the catch can I had oil in th breather like a bitch and small amounts of smoke would also escape...NOW, no oil, only in can, and NO smoke...Im happy...
