Had to pull the intake off to fix the knock sensors, so I decided to do the TBSS intake swap along with the LS6 valley cover swap. Ive read a bunch of info on other forums that mostly pertain to the LS1 swap. From what i have gathered I just need to cap off the fixed orifice pvc on the driver side valve cover, run a hose from the barb on the LS6 cover to the catch can then back to the intake manifold, but my question is what do I do with the port on the passenger side. Should it get capped too? I saw on the sticky for the TBSS intake swap that you have to put a hose barb in the intake tube for the clean side of the pcv system, do I need to go ahead and do that or just cap the thing off. I dont want to cause too much pressure in the crankcase to the point it blows out the rear main seal, should I add a breather on the oil cap as well? Truck is a 03 Silverado SS btw.

Depends on the can. What brand do you have

Havent ordered the can yet. Looking at the AMW, CCA, or Mighty Mouse. Leaning towards the Mighty Mouse. After doing some more reading, it seems that you cap off the driver side, and leave the passenger side hooked up to a clean air source.

Do you need a catch can if you have the LS6 valley? I thought the valley cover was supposed to address those problems in the first place?

You won't cap any with the mighty mouse. They have a diagram on there site. Same can I am running, hose routing as follows for the MM catch can.

Fresh air: drivers valve cover to intake tube after MAF
PCV: passenger valve cover to dirty side can
Clean air exit: other side of catch can to intake

I talked to David today from Mighty Mouse. I can use the PCV can with the LS6 valley cover. If I increase hp such as forced induction it can also cover me down the road. David was super polite and answered all my questions. Plan on ordering one tomorrow.
