Default PCV routing ??

Switched from perimiter bolt to center bolt valve covers and the pass side cover only has the rear most fitting.

I borrowed this pic from another thread:



The rear most fitting isn't there.

I have the front fitting turned backwards and connected to where the rear one should be connected.

What is the best way to hook this up??

The forward fitting and line (red) isn't there.
Do I need it?? Can I block off the fitting on the TB and eliminate this hose???
Yup, you need it. It supplies fresh filtered air to the crankcase. Without it, you'll pull manifold vacuum in the crankcase.
Another option would be to replace the oil filler cap with a breather. Then you could remove and plug that supply line. Fresh air would come in through the breather.
Third option might be to hook the PCV line to one fitting on one valve cover, and the supply from the throttle body to the other fitting on the other valve cover.

Default breather

Most auto supply stores carry them. Be sure to take the extension housing out of your valve cover and take it to the store to get the breather that will fit where the cap came out. If you just try to put the breather on where the fill cap was the breather usually hits the hood.

ECS has one that fits right where the oil fill cap used to go, with no other mods, as on EGs car. Picture of EG's car

You have LS6 valve covers, that is why the passenger cover only has one connector. They have a different PCV than the one in the pic. A breather will work, but you might get some oil in the engine bay from it. I know I would. Also, if it matters, it's not EPA 'friendly', if not go for it. Also, I don't know if you have a stock throttle body, but you will need to cap the hose that used to go between the throttle body and the valve cover. That will be a variable vacuum leak (air behind the MAF). Don't ask how I know.

I 've got the drivers side routed to my catch can and in behind the TB for now.....

I will see if I can get a breather for it.

Sounds like the best solution so far.
