Elite Engineering 6.2L (L9H) Catch Can Issues

[Brendan Cosworth]

I bought a catch can for a 2010 Chevy Silverado 6.2L. There doesn't appear to be instructions on their website for our trucks and I am having some trouble figuring out what the intended design was.

First is what is in the box. It discusses 2 x 10mm bolts on the drawing but I was only given what appears a 25mm and a spacer. There is also a rubber gasket that I am not sure where it goes. Perhaps on the separator inside? It is smaller than the entire unit. I also have 3 adapters for the can, not sure if it is for choice or what.

Second is the stock PVC system. There isn't a clear indication of what the PVC is, but my guess is a very small hose that seems to run from a noise deadning baffle towards the fuel rail on the passenger side. I didn't see a PVC valve and it seems quite small. If this is the connector, the connector into the stock intake is a press in style, not sure if it is expected to cut it or what the idea is.

Finally is the mounting location. Originally I thought that removing the ground bolt onto the block was the location, however once mounted it interferes with the intake and would be impossible to empty it later. If you use the blocks slightly farther up the block I think I would require the smaller 10mm bolts as the 25mm bolt and spacer doesn't seem to make any sense. I also have two crush washers hence why I believe I may be missing it.

Help please, just spent 1.5 hours dinking around only to put it back together.

Yeah I read one, that you linked a bigger one that is 86 pages long. I read as much as I could but there wasn't anything specific about install that I saw. Perhaps I missed it. I was hoping someone had some answers who did the install before because I can't be the only one who this makes no sense to and didn't get instructions.

Pm elite engineering

Yeah I emailed them before I made the thread. Was hoping the answers were quick or someone had a quick link to something. As for the catch can thread. I've re-read it up to page 40 again and so far only the 2014+ 6.2 is being discussed. The new one sure doesn't match our truck layout. I'll keep reading but are you sure they address our year truck? I don't meant to doubt you I am just starting to feel crazy. Haha

[Brendan Cosworth]

Well got to page 53 and saw a post about how 'simple' the old 6.2 is. Maybe I am totally over thinking this. I also wonder if I was playing with the valve breather and not the actual pvc system.

Thanks man. Well I see 2 problems already with what I was working on. What the hell is the little breather on the intake closer to the air box.... haha.

 

Guess I'll have to look at it more tonight when I am home.

Hey Cosworth, I'm in just about the same boat as you, just not as far along. I have a 2012 Yukon XL with the 6.2. I've been wanting to order a catch can from Elite Engineering for just over 2 weeks. I've unfortunately had no response from the company after a couple emails and voicemails. I've read everything I can find on the forums and can't clarify some questions.

 

But I believe the short hose on the passenger side connecting the valve cover and intake is the "intake breather hose". It's purpose if I understand correctly is to breath clean air back to the motor while the PVC on the drivers side exhausts air to the intake (catch can side).

 

Which can did you end up purchasing?

[Brendan Cosworth]

Yeah the more minute details I gather the more it appears I was looking in the wrong place. Crap and I've already cut the hoses to length too.

 

I bought the elite e2 can. I've got a hold of 'steve' I can pm you his email when I get home.

[RyanbabZ71]

hose is cheap at any autoparts store.

[Brendan Cosworth]

So found a suitable mounting point. I'm keeping all the photos to write a how to. Want to check what hose you guys cut though. It seems strange to me since it appears to connect to some sensor.

 

Pictures attached. This is what e.e. told me to put the catch can inline with this.

 

And it comes out of this...

[Brendan Cosworth]

So that is NOT the PVC line as I suspected. Found it through a GM parts site. Going to post a how to because this was way too much research for a non-mechanical person to do if they don't have help.

What is the purpose of a catch can?

I have a 2011 Denali with the 6.2

Thanks
