    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 :)

    +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!

    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?

    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??

    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.
