The 2 links that KingPin1094 posted are some of the best threads that you will find on tech.

Someone always says "buy an LS6 valley cover, it will fix it" and half the time they don't even own one and are just being like a parrot and are just repeating incorrect info. There are so many people who still have the same problem. Personally I think the dual setup is the best option considering it covers all aspects of the pcv system. Not blocking off anything, keeping the fresh air side working properly, no unmetered air, minimal moisture entering the system (breathers) etc.

 

So what's the best way to run a dual catch can? Buy two if the Norris cans?

 

Only advise I can give you is to research how all the brands are made, study their design, throw in the $$ factor and then decide which is the best for you. If the best design is a single can setup purchase 2 of it. If the very best one is an actual dual catch can setup like a Sauko Michi (I know that spelling is horribly wrong) or other dual brand, get that one. First learn what it is soposed to do and understand the function and properties, then design.

When I got mine, I hunted the classifieds and actually purchased both for the same price of 1 new one.

As far as routing, look at the pics and link that both Kingpin and I posted in this thread. Definately read the one thread that Kingpin posted. Its approx. 25 pages discussing many routings and discussing which is the best.

 

Awesome, thanks for all the help!

 

Well I emailed Michi to see if he can get one headed my way. Thanks again to everyone who helped with info and all the links that were helpful as well. Thanks!

 

I read on the thread that the updated LS6 valley cover almost eliminate the need for a catch can. Granted, i have not put on my car yet, but that is what im going to do. And if there still is consumption of oil, i will add a second catch can.

 

I have a AMW can AND a LS6 VC.......love them both !!!!!!

 

It's 10x better than it was without it, that's for sure, but over the course of 3,000 miles I still get about a quarter of a cup of oil in the catch can.

No oil in the intake, so I don't see the need for a dual can on an NA car. I've never had an issue of oil coming through the line from the passenger front valvecover to the TB.

 

Well they said under road race conditions it can, and i plan to drag race so i am unsure if the oil vapor will pressurize up near the valve cover under WOT for 11 seconds. Im definitely going to do both the catch can and the LS6 valley cover. im gonna see if i can find an answer about drag racing, if the second catch can is necessary.

 

Don't get me wrong, it's not going to HURT anything, at all. I'd just rather see you save 100 bucks for something else.

 

Ok, quick question. I have deleted the factory routing of the PCV system due to different valve covers, intake, throttle body, etc. The new valve covers dont have provisions for PCV but I have added a Valley Cover with a vent as well as my FAST 90 with a vent and my Holley TB.

Now I have 3 vents (Valley Cover, TB and Intake) so do I take the Norris can and install a TEE to split vaccum duties between the Throttle Body and Intake?

I also have installed a K&N breather as my oil filler neck. Is that going to spray oil even though I install the catch can?

Picture doesnt work, never mind!

Anyone with a good answer?

Okay after a little more research I think I have decided to go with the Rx can. On their website it's offered in either a single or dual check valve and the difference is like $20 in price. Anyone know the difference. Right now my car is a full bolt and N/A but I have plans in place for a procharger in the future. I want something I can use now and later. Also, if I use the Rx can, because it only has one inlet and one outlet, can I just block off the port on both the front passenger side valve cover and where that line goes to the throttle body? I'm ready to buy one of these but I want to be well informed. Thanks for all the help so far! It's much appreciated.

 

http://www.revxtreme.com/rx-catch-can-dual-check-valve is that it?

 

I'd say get an AMW catchcan, but they stopped making those a while back.. Either way, subscribing...

 

^ Yes thats it. So I guess that running the dual valve setup is what I'm looking for but I do have a question about it.

1. Is there enough of an advantage running the dual valve can with/without boost to justify getting it.

2. Is there any risk with running the dual valve can without boost for now? I will be another year or two before I get my motor finished.

3. With the dual valve setup, what is the ideal way to route all the lines?

Thanks. Everyone has been so helpful.

 

Any one else have some input on the single or dual valve setup? I'm ready to order one just waiting on more info. Thanks again for all the help so far.

 

Well I bought the Rx single valve catch can today. It will be another two years or so until I throw on the super charger so I just decided to hold off on the dual valve for now. I also picked up an LS6 valley cover to go with the system so I'll update with pictures and my thoughts of it after I get it all installed. They said it would be about three weeks before it's at my door. I don't mind waiting though for a quality product. Thanks for the input, links, and suggestions.

 

Good choice....much better than the Norris CC.
