The "Catch Can" Explained!

[SSNvMiner]

I sure appreciate all the information and the I knew nothing of this before reading this thread. I want to for not having one on all my other vehicles. Live-n-learn. . . I ordered an Apex CC today and our SS is not even scheduled to be built for a week or so... That just 'shows-to-go-ya' what creditable information can do. I am going to trailer her home and put it on before I start the break-in!!! Thanks again for all the info.

Oh ... I called Apex Motorsports late today and Paul answered the phone an hour after closing and was patient enough to answer all my questions and even was willing to fire up the system to take my order. Not wanting for him to go through the hassle, I just ordered online. But, I was impressed with the after hour CS. Thanks Apex

Question:

I have an L99 but have done and LS3 conversion for my cam. Do I continue to leave it hooked up as an L99 or do I hook it up as the LS3 and cap off the the valley cover on the driverside?

Very happy to hear that. Thank you for your order and congrats on the new ride.

Hook it up as an L99 and cap the LS3 valley cover vent. The LS3 only evacs 2/3rds of the motor leaving the entire drivers side valvetrain stagnant. The L99 gets a good cross flow flush through the entire engine.

They were worthless, but I'd already watched the video a couple of times, so that was okay.

There were no hose clamps with the can. Is that normal? I noticed in the APEX installation instructions that they use hose clamps. Why would RX be any different?

Finally, there was a short piece of hose with a hard metal 90 degree bend at one end - a barb on the other. No mention of where/when/how to use this piece, but I used it since it made my hoses route a little better. As far as I know, it was just a piece of hose.

I'm concerned about no hose clamps and also the lack of detailed instructions other than to "watch the guy online" and the instructions provided by revextreme online were atrocious.

Should there be clamps on the hoses?

Thanks Rod

I tend to agree with Rod you guys should have instructions printed. It is a pain to go log-on pull up the website and download/print. When all you want to do is install per-paper. I understand it takes money in overhead and labor but Fedex, Staples, ie (Office Printing Shops) are fairly reasonable to print off a few instructions booklets..

As you know I am already bummed out because of my bracket and oil can do not match or align up.. in this thread

APEX >>><<< Why not just make the LS3 conversion to your L99 setup all the time? Doesn't change or hurt anything..just more hose provieded by you guys.. Right or Wrong???

If your saying that as it sits now..(from reading in this thread).. the LS3 evac's ONLY 2/3rds of the engine while hooking up in the back near the driver back of the block will Evac more sludge my words..or in your words "leaving the entire drivers side valvetrain stagnant". The whole point is having a catch can to evac as much gunk out right???

That would simplfy about/delete 4 pages out of the "self-printed by customer instructions".

Suggest convert all LS3 to the L99 setup and print-out for the next customers wanting to buy the Catch Can. Just improving the whole process from the customer end ie "Suggestion Feedback"... that kinda feedback improves somethings tends too eliminate "blinders on" for a manufacture/vendor.

Better yet why can't you pull dirty air from both PCV ports if you have the dual port can with no supercharger? The LS3 and L99 have the same connection ponts..just one is capped off..

PM replied to. There appears to have been some sort of packaging error with your order. We will get in touch with you about fixing it first thing tomorrow.

So does this setup work properly for the LS3 or am I leaving stagnant the drivers side? I was going to order this but this question and the no instructions is bothering me a bit.

Yes, it functions exactly how the factory engineers designed it to function. That comment was made in the context of a heavily modified engine.

We provide extremely detailed instructions. They are 18 pages long and include large color photos. Because of the length we do not print them and put them in the box. We put a card in the box with a link to a PDF file. You can print them or simply pull them up on your phone.

Ok thank you for clearing that up. I will be placing an order some time this week. I do feel though every manufacturer should provide paper instructions. There are a lot of old farts like me that just prefer it that way and not having to bother downloading anything. Then again I've built Pontiac race motors in my day and learned about cars at a young age at a top fuel race car shop called C&FbBauer in NY so I think I can get through a catch can install lolol.

No problem. Thank you in advance.

does anyone here have an elite catch can installed and has heard an air hissing noise coming from in or around the catch can. not too loud, with the hood closed it is only barely audible if you know what your listening for. iv had the can on for a few thousand miles now like this, oil pressure and oil level is fine through all kinds of driving so not sure if this is a problem.
