Catch Cans

[Munz]

Hey Guys

Just wondering why I'm seeing alot of NA guys running catch cans - I understand about being needed for boost but why are they needed on an NA LS1 car?

N E info would be great

Have a read of this Corvette PCV Oil Catch Can

Basically, the Lsx engines have a bad pvc system, and coat everything in the manifold in oil (can be a fair amount, ive seen one lad with puddles of oil in his) so putting the can on stops all that crap hot oily air mixing with the fresh cool clean air comming in and obviously keeps the manifold clean

I deff noticed mine ran smoother and responsed better when putting it on my ve, after a week or so of driving ive got a teaspoon or 2 of oil in there

Hope this helps

I would be keen on a catch can where can you pick them uP from plus i plan on taking my car on the track one day i think you need one or you cant get out on track!

[cpbait]

You can get some good ones on ebay, have a look there, Elite Engineering catch can's look to be the goods from what iv heard.

[WogBoyz]

Yeah ive got an Elite one, very good quality and havnt had any problems with it

[SAMO-87]

+2 for elite. Excellent product, no dramas at all. I pick up a couple of teaspoons of oil after a week or so of driving.

Definatley worth the money!

Yeah same, works very well

+3 Elite on mine also.

I am also keen to install one on my VX SS just a quick question should i buy one with a breather or one with out...and how hard are they to install

[macca33]

Another vote for Elite cans - they are the duck's guts.

I'd buy one that is sealed - as the breather type ones do not comply with EPA rules and you may get pinched if you get pulled up.

cheers

hmm might try one out, did you guys pull your manifolds off to clean them out when you put the catch can in or did you just put it in?

I just wiped in as far as i could to clean the manifold, however mine was pretty much spotless anyway, i wiped the tb down the same way, was also pretty clean

[GM GEN3]

Yeah I'm going to get one does any one have a picture of how it hooks up on to the ls1 motor i looked at some pic and a lot of them are different thanks

[Ss666]

How hard are these to put in??? What benefits would come from a catch can? How much would a shop generally charge to put one in??

[WogBoyz]

Heaps easy to put on, benifits = clean manifold and smoother running/responsive (read link at top of page) as for the ls1 setup someone on here will prob have one fitted so im sure they can help you out

I realise my engine isn't an LS engine.
But I found out on my first track day, that when I started the engine, after sitting in the pits following a track session, the engine would blow a heap of oil smoke out the exhaust for 20 seconds or so. Seems it had dragged a heap of oil into the intake. So before next track day I fitted up a catch can and there was no further oil burning problems. And it caught quite a bit of oil in the can, especially in the early couple of sessions where I was had it sitting above 6000rpm fairly regularly.

Some advice I will offer you from my experience, is a lot of so called catch cans are simply an empty oil can with a couple of pipe fittings. They won't do a proper job of seperating the oil, because there is nothing inside to catch the oil. A proper catch can/oil seperator will have some sort of baffling inside to catch the oil before it gets sucked back into the engine. I ended up buying a catch can with nothing inside (because I couldn't find a proper one), pulled it apart, fit a piece of aluminium plate (with several holes drilled in it to allow airflow) inside dividing it into 2 halves (inlet side and outlet). Then stuffed some stainless steel wool into the inlet side so it would catch the oil. Worked a treat.

[WogBoyz]

Yep what he said ^ the elite however is very good qualtiy and has heaps of that steel wool looking stuff in the top part

[GM GEN3]

is this how it goes i found this pic

[DLFHUB666]

^^^ that is a vy on setup vt/vx LS1 have a different setup. Just thought i would let people know.

[GM GEN3]

Does any one have a pic of the vx ls1 set up cos i couldn't find much

[DLFHUB666]

Hey Gm gen3, dont have a pic but let me see if i can explian it . In the pic you posted.The oil/gases get sucked out of the valley an put back in the manifold. The vt/vx setup takes the oil/gases from the back of both rocker covers an then puts it back into the manifold. sorry if this dosent make sense but i tried editing the image you posted but it wouldnt let me upload it after i did.??? im no good with computers.

[WogBoyz]

thats the same setup as mine, the crapy air from the manifold goes into the can then goes from to the can to the manifold with cool clean air

The top one is what you are after.

Basically just diconnect the hose from the manifold and route into the catch can, then the catch can back into the manifold.

Kevs spot on. Top one is the vt/vx setup, bottom one is vy onwards.
