Hey guys,

I did a bit of searching around on the forums but couldn't get the answers I needed.So how exactly does an oil catch can set up work?

Although I have a very faint idea on how the pcv setup works (releases the blow-by gases from the crank case),I haven't understood the oil catch can set up.

So the questions I have on this set up are:

-Does it increase the performance of the engine?

- Is there any gain from it on a stock engine?

-What are the possibilitys in terms of plumbing and blocking off to accommodate this set up?

-If you are using the stock intake pipe,do you simply block the hole where the piping previously connected up to?

Thanks in advance.

Hey mate the way I understand it is that the catch can collects any oil that is getting thrown into the intake pipe. and lets just air go into the intake or vents the air to atmosphere depending on how it is all set up.

As for if there are any gains or performance on a stock engine i don`t think so. Some people may think there is but personally I see it more as trying to make your motor run better.

And with blocking off the intake i normally run mine with one pipe coming off of the cam cover into the can and then from the can run a hose back to the intake. It still works this way and gives you one less reason to be picked on by the jacks.

Easiest way is to get a good baffled one vented to atmosphere and run two hoses (one from each valve cover) directly to your catch can. Depending on the condition of your engine, it may pick up very little blow off or it might be quite a bit.

this is how i run mine... the intake is blocked off, both cam covers go to catch can, can vents to atmo and cam cover to plenum is left untouched

Isn't vent to atmo illegal? would the cops defect you or something?

So when you run the hoses from each cam cover to the catch can to vent to atmo what do you do with the intake hole?

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.

      There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
