You want to use a catch can, and this is one of the best in terms of design and quality.

1997 Corvette Oil catch can
I am nearly finished with my heads/cam/intake build on my '97 corvette. I ran into a problem hooking up the hoses for a pcv valve. I had to get center bolt valve covers, and I need to run a hose from the rear of the drivers side valve cover into the side of the LS6 intake manifold. Problem I am finding is that I will either need to use an oil catch can, or try to find an inline pcv valve to work with the setup I have. Does anyone have any suggestions or know anyone selling an oil catch can? I would feel better using the oil catch can on this setup anyways.
Thanks

I personally wouldn't get a catch can since it will take up so much space in the engine compartment. I'm not a big fan of catch cans. I don't think they're necessary. I don't think there are any factory setups with one. All they ever use is a baffle on the valvecover and then the pcv valve.

Where is this coming from? A catch can is a great mod for the LS1 motor. i had big issues with pooling inmy intake manifold and installing a catch can stopped the problem. Catch cans don't come on cars because it's too expensive to put them on from the factory. I think the majority of people on this forum would agree that a catch can on an LS1 motor is a fantastic mod that eleminates the inefficient and faulty stock pcv valve.

I'd stay away from cans with brillo pad filters for a few reasons, the first of which involves the large diameter wire that is used. It is not small enough to trap much of the airborne oil droplets within the blowby gas that sails through.
Yes, they will trap some oil.
But yes, they will allow oil to coat the intake, albeit more slowly than not having anything in-place to catch oil.

It is a good idea to keep the intake free from oil. I had two pistons on a supercharged engine crack probably because of oil getting into the intake; which burns a lot hotter than gas, which isn't good.
But does the Z06 or ZR1 have a catchcan? Does a 911 or other performance car?

Thanks for all the advice. I ordered a catch can. Now the problem I am having without doing the LS1 to LS6 pcv conversion, I was told to splice the hose running from the rear of my drivers side valve cover into the catch can and connect an "inline" pcv valve in between. Has anyone done it like this?? If so, how did you do it and what pcv valve did you use, part # etc..
Thanks so much. This is driving me crazy

Just becuase a production car doesn't have a catch can doesn't mean it's not a good idea? Companies are in the business of making money. Adding a 100 dollar catch can to each car drives up its cost in the millions. If they can get away with a system that does essentially the same job for cents on the dollar, as a business it makes financial sense. That is why you don't see them on production cars.

I would install a LS6 valley cover they are around $75---You seem to have installed a LS6 manifold already---This mod helps with oil from getting into your intake via the PCV system---
The LS6 valley cover re-routes the PVC intake hose to the middle of the valley rather than from both sides of the valve covers---Then you either just plug off the drivers side PVC hole OR install an atmosheric breather there ( in a no smog state) or swap the plug and breather when getting it smogged) I installed a breather--- here is a link to a LS1 to LS6 valley cover swap and shows how the hoses are routed and lists all the parts you'll need

This is what is sticking up from the rear of the drivers side valve cover. This is a track only car and I was told to put a breather here instead of PCV. what would be the best way to add a breather to this??

Small piece of 3/8" hose ----2 small clamps and a small breather that has a 3/8" male hose nipple on the bottom--Kragens has them--for about $10 or less--The K&N ones are too pricey--but they may have them too-The tops have about a 2" diameter-- if the hose fits tight on the nipples you won't even ned the clamps---
