Oil catch can?

jrob56 · February 17, 2016

So I have a stupid question and I feel stupid too. On the elite e-2x catch can, what happens if you install the hoses backward? I was going through some things and found that I didn't install the high flow check valve. So i went online and this time they had a video on the truck so I took a look at it and realized I mixed the intake and exit ports. I think I should be fine since I didn't have the high flow check value. I did collect a bunch of gunk /oil the last time I checked it about a 3 weeks ago and just now. I have only used it for about 1000 miles. I fixed it now and I have switched the cables around and added the check value on the exit port (one on the side not center!).

I took the can apart and i looked inside and the center had a tube that went down 2/3 of the can.

I feel like an idiot.

Since no check valve shouldnt hurt anything, just dont think it would have collected very well. If you had the check valve blocking it, you would have had some excess crankcase pressure which I believe can end up in a seal blowing out and a nice leak.

I got lucky for not putting the value in. I don't think I did anymore damage than I would have not having the catch can as it was all going back to the oil. Shockey I did still manage to collect a lot. This time I have it all setup correctly with the value in place and I'm the right direction.

Since you were talking about check valves has anybody or is there any reason to put a check valve on the exit hose (from the crankcase)? That way stuff doesn't run back into the crankcase when you shut down? Thoughts?

So what is different about the E2-X and the E2? I ordered the E2 this week and it should be here Friday. After reading this, I'm almost having second thoughts about the E2. It seems like the E2 works just fine for our trucks, but wasn't sure what made the E2-X the best for our trucks. But I only have 550 miles on as of this evening so I shouldn't have much to worry about. Heck, I'm still on my second tank of gas! I know being in Nebraska I will have to drain the can more often, and fortunately my truck gets parked in the garage so I shouldn't have to worry about the overnight freeze, just during the day when I'm at work.

The E2X has a different internal design that allows it to trap more oil and contaminants from the PCV gases. The E2 is still a good can but the E2X will basically filter more.

_{The E2-X also contains a lot more goodies than the other set-ups. That is why it is more pricey.}

_{The standard can for $159 is nothing more than the can, two fittings, hose and clamps.}

_{The E2 can is a bigger can for a few more dollars and you have the ability to go to a second inlet system for blower motors and aggressive driving.}

_{The E2-X system comes with the can, hoses, AN fittings on the can, check valve, and the clean air system.}

_{By the time you add up all of the extra goodies you are not paying much more for the oil can itself. However, it is a far superior design, bigger capacity and has a built in ball drain valve. If you really want to be the cat's meow, throw a brass hose barb on the drain add a piece of 3/8" drain hose and zip tie it to something down low under the truck. Then you can just kick a drain pan under the truck in the predescribed location on the bottom of the hose and turn the drain valve from under the hood and you don't even get your hands dirty!}

Correct. All Elite cans have designated inlets and outlets. Hurt nothing, just not as effective.

Excellent description!!!

Yes, the AN fittings alone and the drain valve are over $100 if purchased separately, checkvalves are $16 each I think so when all is added up it is the best bargain as most want the professional look of it all VS bare fittings and clamps. Then you look at the E2-X as their most effective release to date the decision is easy.

I had read a post by a guy on here and he complained about the cost difference from the standard can to the E2-X. I had already made my mind up I was going with a catch can, clean side separator and a check valve. I then was tempted by the braided hose option as well. I ordered the standard can first (love the colors) and before install realized I was going to do the E2-X. Returned it, and then realized the E2-X came with most all of the goodies I wanted! Only got to do the braided hoses and I'm good to go. I decided to hold off until I was happy with the installation and will get hoses cut to fit, since they are a bear to cut cleanly.

PS: Just an FYI for all you guys that can't figure out how to put the 3/8" rubber hoses on the AN fittings on the E2-X can.... The fitting comes apart and you just slide the end of the fitting over the hose then tighten it back up.

Well I guess in this case some is better than none. It hasn't been delivered yet, so maybe I can return it for the E2-X. Maybe I can convince my buddy to buy the E2 and I'll upgrade to the E2-X!

Forgot to post these when I installed the can but here is my dual exit catch can installation. GDI, thanks for your help and input on these catch cans!

GDI Tech · February 19, 2016

The check valves go on the 2 outlets (outer fittings) and that will control flow. There is no way for any of the gunk to flow back into the crankcase due to the design, but great question.

The AN fittings work with either standard hose or the braided lines. Use a bit of grease for both to make inserting and tightening easier.

The E2 is a dual outlet larger version of the E1 and is great for port injection engines that can tolerate some ingestion. The E2-X is the best most effective system on the market as far as stopping 95% plus of this and is what I would only run on the GDI as you need to stop all of this. And the dual valve is also giving the best evacuation so that also is my choice. The E2-X "Ultra" is fro big boost, big power builds and anyone living where the winters hard freeze it is double the capacity of the E2-X.

Cleanside I suggest for any of the Elite cans...it is addressing the only other point of ingestion.

Hope that helps!!

Believe it or not for vehicles in the North that go through winters, it was recommended to me to not run the clean side seperator because it dumps the moisture back into the engine.

Not the Elite version with the dual valve can as it converts the PCV to always evacuate, not just at idle, cruise, and deceleration like the stock PCV system does. But for the stock GM cleanside unit that is correct.
