bringing back this old thread, bought one of these today, and didn't realize it was the oil one and not the coolant reservoir one, but oh well, just gonna get both.. so any how to on this? or anyone have any pics?
If you look at the attached picture, you can see the oil catch can located on the bottom right of the bov, using the coolant reservor tank's bracket. If you follow the hoses in the picture, it hooks up between the pcv valve and the 2 vacuum ports on the intake manifold.
So one line connects to the pcv valve and other other line connects to the tee of the 2 vacuum ports. Make sure the oil catch can does not have any other open holes, or the car will have a vacuum leak. It must have sealed connections.
As for the vacuum line on the valve cover to the intake pipe, you can either leave that or remove the line and just throw on a breather filter on the valve cover and cover up the intake pipe hole. That is what I did as well.

ok, I thought that the oil catch tank went inbetween the valve cover port (one that you have the breather on now) and the intake pipe.. because I am not sure how I can hook into the PCV valve with the 2 vac lines going into it from the IM now, and where did the other line go again.. I saw one connecting to the PCV valve (not sure how, I guess just tighten a lot onto the hole?) and than is the other one connected to the part where the 2 bigger vac lines from the IM connect too? heres a pic of my setup right now... and I guess the point is that is is suppose to be inbetween the valve cover opening and the IM and not between the valve and the intake (which the way you have it set up I guess cuts that off too) so I just take that connector off the PCV that, I guess short silicone hose that T's into the vac lines like I said before.. hmm, LMK, thanks a lot for the help, sounds cool

You can hook it up between the valve cover and the intake pipe, but is not as effective. The objective of using a oil catch can is to eliminate the need of the pcv valve system. From factory, the car has 2 systems in recycling the extra oil and fuel. The first way is the pcv valve system and the second way is the breather line coming off the valve cover.
The breather line vents the extra fumes and gases out of the head to relieve excess pressure, so that line needs to be going to the atmosphere. The breather filter allows filtered air into the valve cover, but does not allow any oil or gas to be sucked in by the air intake.
The PCV only is used when vacuum pressure is created by the engine. At full throttle, it remains closed and it idle it should be open. That being said, you want the can to catch all the excess oil/fuel into the catch can and not back into the engine.
Just do it the way I explained it the first time, it is the best way to do it and allows none of that crap to go back into the engine.

Im so confused D: someone should do a Diagram of how one is installed... I want to get one but I dont know waht I would fuly need to do to install.
Lol, it is alot easier than it sounds. There are two lines coming off the oil catch can. The oil catch can hooks up between the pcv valve and the vacuum lines. So, one line from the oil catch can goes to the pcv valve, and the 2nd line from the oil catch can goes to the tee of the vacuum lines. Here is a picture from paint

ya actually after looking at my car for a little while I got what you were talking about, at first I just didn't realize that there was so much fluid and oil that got recycled around like that.. who knew!.. so now I am definitely sticking this in there, its pretty sweet actually.. and I assume that when the oil catch can gets filled up I dump it right.. don't want to reuse that crap?
but as far as the install, I think I might need more hose from somewhere, any reinforced hose like that is found with kit can be found at a hardware store right?.. theres nothing really special about the ones that come with it?.. and also so when I hook it up, 1 hose goes to the (can I hook it up right to the 90degree bend on the PCV valve.. and than the other one I can find a hose connector piece and hook it into that silicone connector after the 2 vac lines meet together going to the PCV (so basically the catch can goes in between where the PVC 90 is and the start of the hose part going to the IM).. and also when I installed the 626 IM, I noticed that the PVC is really just "loosely" plugged almost into the valve cover there isn't really any strong connection made there right? just curious for when I put the can in, want to make sure the hoses don't pull that out at anytime..
also lastly, your mounting, did you mount that right on the other side of the coolant fluid bracket?.. I gotta play around with where I'm going to put mine, but I think the Injen might be in the way for me to do that.. so we will see, just wanted to see if that is where you have yours (think that is where it is in the pic).. thanks a lot. made putting this in much easier, and gives me more incentive to put it in.. knowing how it helps.
oh and also outlaw, if you don't get yours in soon when I am out of school in a couple weeks I will be doing all this, so I will take some pics closely for the install and all that, like to keep my installs documented first time around.. at least parts of them
EDIT: just realized this, but I assume that I watch the fluid and crap that comes out, and I would want to watch the oil levels and fill with new oil as necessary right (into the actual valve, for the oil that is coming out into can)

ok, so I got my oil catch can, and the coolant resivoir also, and I wanna put them in, I have an idea that I will make a bracket that is like the stock one for the coolant but just ticker and bent properly so that I will be able to just bolt the coolant in the same general area as the stock with a similar bracket piece..
but for the oil catch can, I am thinking.. under attached to the frame or something, like under my CAI, with some rubber washers for the vibration.. anyone have any other ideas about how to mount these?.. underneath just seems so low

lol, well I will do that once I get back from school and my trip.. so early june I will do that, I have an idea where/how to mount this, just don't have the time now, and wanted to get some other ideas first.. should be fun actually, gonna do the AWR side mount inserts at that time too, and the ss clutch line I got coming in

ok so got it installed the other day, worked out pretty well, I would do a How to: but it's gonna have to wait till I get some free time, but I will link some pics of the process, should be enough to give you guys a heads up

hey jamesk I installed everything as seen in the pics, but I have been getting a check engine light for a split second when I let off the gas after boost I think, but it goes away right away, I am guessing that is mostly because of the HKS venting to atmosphere, so I might just get a recirculating attachment and stick that into where the valve line use to connect to in the Injen because I have the breather in now..
but do you think that the breathing being in there is letting out enough air to affect the MAF readings at all, or is it most likely just the BOV venting, and the breather doesn't release any or enough air?

ya the oil catch can is, but I meant the air that might be getting out through the breather, because I stuck the breather in the valve cover spot where it would normally be connected to the Injen intake, from what you were saying I assume that it's pretty much only fumes that are getting out of the valve cover that would be connected to the Injen, or is there oil that can leak out that way too?

The issues you would be having with BOV would be stalling. I've never heard of it being a check engine light thing, and if it was triggered by something like that it would stay lit till the next read cycle then shut off. what your explaining seems to be from a different sensor, I would guess your oil pressure or oil level sensor. Check your oil are you short a quart or 2? are you running an oil pressure gauge? what are your reading?
I actually had oil in my intake pipe and installed a breather at the vent eliminating the hose to the intake to see if the oil was backing up and coming in that way. only air came out the breather and I still had oil in my intake. I ended up having the oil return line kinked under the turbo

ooo, thank you very much for the info, well I am pretty sure I am set on oil since I just changed it, but that sounds just like what is happening with me, because I still have some oil streaking my IC hot pipe near the turbo, but couldn't figure out what it was, so I will check the oil lines for kinks, which oil line would it be, that black one that goes into the turbo right?.. or is it the one that is under?.. haven't really looked at that one but I will check that one out too. thanks, that's actually why I installed the breather also, wanted that oil out of there
and no I don't have an oil gauge, I should probably get one sometime this summer
