PS... I think the hoses in Billy's pictures are backwards, the hose coming off the bottom of the engine fitting needs to be installed in the top fitting of the catch can and the upper engine hose needs to be installed in the bottom fitting of the catch can. The crankcase vapor needs to flow DOWN through the catch can so the oil will coalesce on the metallic filter and drop to the bottom of the can with the remaining vapors drawn into the motor. Not a perfect solution, but better than no catch can at all. There are other methods too, one is to use an air compressor filter/coalesce fitting that may further condense/collect the oil out of the air/vapor than the steel mesh type used in the EE product.

Thought I would link this thread to another in the Z06 section on same topic. Good information aobut catch-cans, and some additional explanations of what they do, and why they are beneficial.

To the people that use them...
but please do not tell the other 99.9% that we are harming our motors, because we ARE NOT.

Again, so what? Seriously? My big block 427 on my 1969 Camaro uses a PCV valve to evacuate all the oil vapours and such from the crank case (then it goes through the manifold into the combustion chamber). This has been happening since the beginning of time. 99.9% of people DO NOT use them in their Vettes with NO adverse affects. People say GM reads these blogs, the LS motors have been around for over 10 years and GM still does not incorporate these, go figure. To the people that use them... but please do not tell the other 99.9% that we are harming our motors, because we ARE NOT.

You can keep posting and I can keep posting. Neither one of us is going to change anyones mind. While nobody is going to "hurt" their motor or blow up because they don't have a catch-can.. there is proof and explanation behind how using a catch-can, can be beneficial (performance). It's out lined in several places so I am not going to repeat whats been posted already in the other links.

Catch cans
When I had Jeremy Formato provide/install/tune my LS2 with his ported Intake and TB, he told me there was an appreciable amount of oil in the stock intake and that this was typical to LS engines for the reason Talon90 has so aptly described. I installed a catch can as a result, and am happy to have done so because it is inexpensive, easy to install and monitor and I consider it to be a useful preventative measure to prevent oil accumulation in an area that is clearly NOT intended to have oil accumulation. It accumulates during ordinary driving as well as track applications because it is a function born of normal engine operation.
Elite Engineering is a U.S. Corporation located in Colorado that makes a variety of top-notch parts for the C6 Corvette and is a Forum vendor. Both Talon90 and Willfulone (Chip from CCA) are both well-respected Forum vendors. Anyone choosing to purchase this useful addition from any of these brothers in arms will be pleased and satisfied.

You are correct. In my pics the hoses are reversed and I corrected after taking the pics.
As far as emptying the can, you should be able to remove the fuel rail cover to give you a little more room then unscrew the bottom 1/2 of the can to empty. If there's not enough room that way, just loosen the bolt that attaches the mounting arm to the block enough to move the whole can a little and you should be able to unscrew it then.
I installed a Vararam CAI and no longer have the resonator box so I went back and installed the spacer that came with the Elite can and it is out in the open now and easy to get to, to check/empty the oil accumulation.
If you plan to install a CAI at some point, leave the hoses about 1" longer so when/if you reinstall the can with the spacer they have enough length. I did not do this (hind sight is 20/20 you know) and my can is at a very slight angle instead of being perfectly straight up and down. I may replace the hoses at some time but it's not a big deal to me either way. No one ever looks at it but me and it's only very slightly tilted

I guess there's two types of vette owners.
1.) Those who will argue to the teeth why they *shouldn't* do this, that, whatever.
2.) Those of us who want to take car of our beautiful Corvettes and see them perform to their potential.
Note: if you've ever opened your intake manifold and seen that gooey, gunky oil build-up that comes from just a few months of normal driving conditions, I suspect you'll move from the 1st category to the 2nd

LS3 Install Question
So I have a LS3 but I have a Vararam CAI installed does this eliminate the issue of the resonator box being in the way? Is so then the install would be just like the LS2 install correct?
