Hopefully someone here can help me with connections on my E2 catch can as I can't get any response from Elite Engineering. I've called and left multiple messages, I've emailed multiple times and I can't seem to get help from them. I purchased the catch can a couple months ago and i'm ready to connect this but I've done some upgrades on my 01 Z06 and it's not a standard setup. The catch can is a single inlet with dual outlets and on the engine i have three ports to connect to (valley cover, passenger side valve cover and FAST 102 intake). The throttle body is now a NW 103 and it doesn't have any vacuum ports.
Based on what I'm interpreting of what you have, I suggest you look at the figure on the bottom of Page 5. Center port of the Catch Can connects to your valley cover and/or your passenger side valve cover and the outlet will connect to manifold vacuum. Simple as that. The second outlet can be plugged. If the Throttle Body doesn't have a vacuum port, you need to find an available port on the intake manifold for your outlet connection. Good Luck!
This is how mine is setup. the pass valve cover is for CLEAN air from the intake and will not tie into the third port, block it, I tapped into my air bridge for it with the ls2 TB/Fast. You only need valley cover IN and OUT to the fast.

Ok this is making sense now. What are you using to tap into the rubber hose on the air bridge and is it the hose that is connected to the very front of the TB? Are using a PCV between the catch can and the intake?
If you have custom work done, I’d return the elite can and go with Mighty Mouse. Much more versatile and customizable.
nevertheless, I will try and help you. Post a photo of your passenger side of motor with the fuel rail cover off. Also, I think you’re confused about connections. You don’t tap into any hoses off the air bridge. It’s hard to answer the question without seeing what kind of modifications you’ve made. But I’m guessing you still have the pcv connection from the ls6 valley cover to the install manifold? Should be a small loop.

Not sure how I'd return it as they wont answer/return my calls or emails lol. So there is the connection on the front passenger side of the valley cover, the passenger side valve cover and the front passenger side of the FAST intake which all 3 of those are original factory locations. The only difference is my 103mm TB no longer has the hose connection that would go to the passenger valve cover which seems like I've seen guys install a bung into the air bridge and run it to the passenger valve cover for the fresh air. Also is a pcv valve still needed with this setup?
Thx!
For an LS6 motor or an ls6 valley pan..... 1. Is the inlet into the can. 2. Is the outlet from the can.
again, I don’t know your build. And I don’t know your mods. But this is the setup for many ls6 stock motors. Check out yellowvette04 on YouTube. He just installed an elite can on an ls6 valley pan. You may have mods that change this so I would double check with someone who is knowledgeable about your build.

The valley plate port is your PCV valve... So it needs vacuum pulled on it. Your port on the FAST is where that vacuum comes from.
You go from your air bridge(or coupler) to the passenger side valve cover because thats your clean air inlet and you want filtered air going in there... Alternatively you can get one of those little 1" filters and put it on the passenger valve cover port...
The valley cover to catch can then catch can to intake totally makes sense. Are the breather caps for the valve cover sufficient vs running from the air bridge to the valve cover? I'd rather not mess with putting a port in the air bridge if I don't have to.

When watching yellowvette04's video he mentioned 01 z06 needs the pcv valve. Tony Mamo specd most of my engine build and he mentioned running the valve cover and valley cover into the catch can inlet and block off the FAST intake port and then daylight the catch can outlet. He said to keep any dirty air out of the intake. Thoughts?
You have to feed the engine crankcase fresh air. It comes from a filtered source. In this case the air bridge is ideal. I use a rubber grommet and a 90 degree hard plastic elbow off of a PCV valve.
You already know where the other two go. Inlet is from valley cover and outlet goes to the intake.

The valley cover is PCV... it is NOT a vacuum source. The valve cover while I would say its a "vacuum source" its not full vacuum from how I understand it, at least not full vacuum like the intake manifold can produce. Hooking up a catch can like he is telling you to do will accomplish nothing as you need a vacuum source on the catch can if you hook PCV to it.
Your catch can will go between the valley cover i.e. PCV valve and the FAST intake(vacuum source). The catch can is what will keep the dirty air from entering the intake manifold.
And hooking up a vacuum source(valve cover) AND a port that needs vacuum(valley cover PCV) to the inlets of the catch can IMO will simply allow dirty air to bypass the actual catch can inside the lid. You need a vacuum source hooked to the outlet of the catch can in order to pull the air through the catch can.
Perfect! So it looks like I need a 6AN weld on bung and a 90 degree 6AN Female to 3/8" barb to get my clean air feed to the passenger valve cover. Then I will run the valley port into my catch can and out of catch can into my FAST intake.
So my last question is do I need the PCV valve and will it go between the catch can and FAST? The reason I ask is because it seems the 01 Z06 still requires the PCV Valve.

So on the 01 Z06 like mine do I still need a separate PCV valve? It had one on the stock configuration.

Thank you!
The tap on the valley cover IS your PCV...
I know something changed on that between 01 and 02 to try to get the oil consumption under control. Did the 01's originally come with the LS1 style valley cover(basically smooth, no PCV nipple, just knock sensors) and an external PCV?

I'm not sure of the change but my 01 had the nipple on the valley cover and the PCV valve inline on the short hose between the valley cover and intake. I think 04 was the only year with the PCV built in to the valley cover. Elites website shows using the PCV valve between the catch can and the Intake for the 01-03 z06 so i will follow that unless i am told not to.
2001’s (my setup) have an external pcv line which contains the valve and is number 1 in the photo. Number 2 is the connection to the intake manifold.
late cars have the ls6 valley cover and it ELIMINATED the external pcv. Your pic shows the integrated ls6 style pcv. Thus, barring any other mods that I am unaware of, you install your can just like I described above and just like yellowvette04 did in his video.

Ok so how can you tell by looking at my picture the PCV is integrated? When I pulled the engine apart the valley cover did look like it might have been replaced but I'm not positive.
