ok so this is where my oil can goes.. it collects about a quart or less every year maybe?? theres another spot for the can that also helps alot.. but, this is just my install pic for those who asked.. you can place it many ways on its side etc.. it just uses gravity to keep oil from, the return line..

Nice spot.

You do know you're missing a clamp on the SRI/TIP though, right? Should be 2 clamps where the metal sleeve meets the intake, one on each side.
 
Nice spot!! i made it work with a wider version of a silicone specific clamp.. the ones COBB gives you are too small and strip the silicone very easily.. these are wider and keep the worm part outside.. so theyre good..

Hmmmm? That hose is only the fresh air inlet for the main crankcase ventilation system. The PCV valve and OEM oil separator is located under the intake manifold on the block. In all actuality, that OCC isn't doing anything for you... A functional OCC should be in series from the intake manifold main vacuum inlet nipple(on back side of intake manifold plenum) and the PCV on the block. You can mount the OCC with long hoses in the driver wheel well, or use shorter hoses and mount it at the horns under the passenger wheel well...
 
Fresh air inlet?? huh?? air and oil is being drawn out from the crankcase.. not going in?? youve obviously got it backwards!! look at your hoses and their directionality.. the crankcase blows OUT hard on every shift and shoots oil out!! ive seen this many times on dyno pulls.. if you dont believe me run a crankcase breather and see how oily your engine bay becomes?? and like i said there is ANOTHER spot for running an oilcan.. which will catch even more oil.. but, this definately keeps lots of oil off the turbo and inlet.. if you dont believe me?? send me your address and ill mail you what comes out??

Yes, it is truely the fresh air inlet for the PCV system. I have no doubt you see oil/vapor come out of the hose when you let off the gas under heavy boost load, so you don't need to send email. I would post up the PCV system diagram/description so you can see how a PCV valve/system works, but I don't have it handy. You can search the web and find it I'm sure. In almost ALL phases of engine operation filtered air is drawn INTO the cam cover via the hose. Lots of people like to remove it completely and run a little colored filter on the nipple for looks.

That top cam cover hose will indeed vent oil/vapor under boost when the PCV valve is closed IF you have a excessive crankcase pressure or too much oil in the cam cover vent reservoirs. The excessive pressure can be caused by several factors, including compression ring blowby, oil too thick, oil level too high, and/or PCV valve either plugged or stuck open.

The point it that the upper hose is NOT the primary entry point for oil/vapor into the engine. Yes, there may be some oil/vapor injested into the main inlet post MAF, but that area is benign unless you have other issues.

Some people run OCC in both locations (PCV and top inlet) on very high boost applications that create a tremendous amout of ring blowby, but the top location would be the LAST place to add an OCC for actual excessive oil collection. I'm not going to debate with you about it further. You can do whatever you like... YMMV
 
+1 on what forzda says. that is not the ideal location for the occ. you want it in line with with the pcv which is down behind the intake manifold.
 
like i said theres 2 points for a catch can.. skipping this one is just stupid.. you will end up with messy gunk all over your inlet and turbo.. this is too easy to pass up on doing.. use it or dont?? I dont care.. but, your criticisms are off. i already said theres another place that catches more volume and does more.. but, thats not what this unit is for.. this is for catching the vapor that returns to the inlet.. so your points ARE OFF.. youre simply posting to be critical of something you dont understand, solely for the purpose of being a smug superior ass.. please take your TUDE elsewhere.. its absolutely counter productive to the learning experience..

FORZDA.. if youre SO smart?? please post your install thread for the proper location of an OIL CATCH CAN.. id love to learn from your wisdom.. and dont post a link.. do it yourself.. id like pix.. not tude..
 
trust me i know all about it and so does forzda. you may catch some vapors where it is but air is pulled in through the breather when you are in vacuum and evacuated through it when you are in boost, its as simple as that. so more times than not it is used to pull air into the crankcase. if i have to draw a picture how it works i will.

ill draw you the pic.. this unit keeps oil off your inlet and turbo.. end of debate!! even you know that.. if you dont wanna use one.. dont.. but, quit wasting your time on this massive crap pile you call posts.. you have made no points and provided no direction.. put up something better?? instead of slagging all day.. this is just so week.

what is it you think youre debating??

are you trying talk me out of using this??

quit wasting everyones time.. youve posted no reasons NOT to use this.. just that everyone should do exactly as you say?? just like forzda?? you guys are just plain rude.. i dont need your help or advice.. nor would i take any from either of you snobs.. maybe you should move over to the evo forums they love this kind of tude!! and live for endless pointless debates just like this!! youll feel better there..

Well mark, the only "tude" I've read in this entire forum over the past few years is from you. Are you about 19 or so? It is pretty arrogant to tell me to "do it yourself" when I really don't give a crap whether you learn anything or not because you've already proven to me that you're incapable of intellectual gain. Yes, I'm light-years ahead of you, young silkscreener. Isn't that kind of like an "artist" that paints by the numbers?

The main reason I post at all in a crap thread like this is to maybe help those people who may make the mistake of believing even a shred of the misleading technical "information" you post. Enjoy your silly bling, or maybe you'll just post it up for sale like in 95% of your forum posts.

One more thing... I don't feel the need to show or prove anything to you, so take your "tude" and shove it up your ass, while having a nice day!
 
Ha the oil that gets by that breather is negligible. I don't care if you put it there or not. I'm saying the occ you should be more concerned with is putting one between pcv and intake manifold where probably 100 times more oil gets by. but hey you think you know it all, thats fine. i'm not saying you aren't going to get oil there i just know that when i take my intake off and my intercooler pipes i don't have any oil in them there so i don't care to put a occ there.
 
that is correct, but his isn't incorrect, its just not as useful as putting it in the other location.
 
As usual, Steve (with help from COBB) comes through...guess my next mod is going to be the OCC.

I've considered the OCC, but I'm still holding out on the new PCV whenever that decides to show up.

Yep, Steve sent me a PM on topic way earlier and I failed to heed adequately. Even with a revised PCV valve, I think there is a definite need for an external reservoir such as an OCC. The "best" OCC is up for debate, but there is no need for the second PCV valve as in Cobb's version if you use a top quality OCC like this one http://www.saikoumichi.com/Stage2OCC.htm It will handle any amount of boost your turbo could possibly produce. This is the one I run.

I've also attached a couple of photos of the engine block itself so you can see the OEM oil separator/PCV valve setup location. For those who may not recognize it, the black object is the oil separator/breather assembly and the little green doodad is the PCV valve. I also included a bare block photo to show the drain cavity behind the OEM PCV/Cover and the knock sensor location just above it.

And for SOME people who really need it, or are simply curious, I've attached a small document that effectively lays out some pertinate details on blow-by and PCV systems. Enjoy...

I've been waiting, waiting, waiting for this as well...the OCC would be a nice stopgap until that magical day.
 
Thanks for the extra info Forzda, as always, here to help with the facts.

I don't doubt that you're right in that adding the OCC is a good move, but right now I'm too lazy/cheap to do one, and if I'm going to do it, I'd want to do it right (SM OCC with a proper bracket and lines). I've stalled out my spending on extras at this point and am enjoying the car for now.
