Braided vinyl tubing is 5/8" x 3/8". The packet with the pink top is a 1/4" square head plug btw. The rest should be self explenatory.


I've been debating about making a mesh insert but ...too much work without much benefit. Instead I used STAINLESS STEEL brillo pads.

About the rct003. @ $30 + free shipping it's a great investment for what it is. I actually am debating about flipping it upside down and.... I'll leave that for another time.

So here we go.

No Baffles. No screen. Nothing.

However.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1244.jpg)

Good thinking.

It could use a filter media though.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1249.jpg)

2 fluffed brillo pads. You want to stretch them and put them in longways so they end up side by side, instead of one sitting on the other. This way they'll stay tight against the wall.

It should look somewhat like this.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1245.jpg)

The "L" piece is actually an open drain that can be used to feed back into your oil pan if you had a rotary and didn't want to empty it every session. It's rather useless for the k-series though.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1248-1.jpg)

So we plug it. With a 1/4" square head plug.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1253-1.jpg)

Screw the top back on and pop your hood.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1246-Copy.jpg)

Make 2 1/2" incisions on the edge of the buldging part of your battery cover.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1256.jpg)

You can go ahead and feed the hose clamp through.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1257.jpg)

Drop and fasten that shananagan. I put a sticker behind the indicator tube in case there's gonna be something to see there one day.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1258.jpg)

Anyway.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1246.jpg)

Loosen these clamps.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1255.jpg)

Now move the piece above my middle finger out of the way. It actually has 2 purposes so if you wanna get rid of it you'll have to do the same thing you did with your TB bypass. Piece of cake.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1259.jpg)

You want to put the barb splicers into the tubing first cause it's a damn tight fit.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1260.jpg)

Now push in the other end.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1263.jpg)

Make the hoses shorter if they seem to long. Throw 2 Hose clamps on the end of the hose by the catch can.

(http://i20.photobucket.com/albums/b204/mattness138/OBX%20Oil%20Catch%20Can/DSCF1261.jpg)

Everything tight and snug? Good.

Sit down. Have a cigarette. And clean up your mess.

Now we'll see how much oil goes into the combustion chamber on the K-series. Stay tuned for updates and tweaks.

Looks good.  I'm gonna have to re-read this and pay more attention next time when my mind isn't mush.

so what does this do exactly?

I did this mod on my v6 am a take few pic's and you wont believe How well it works

I'm pretty skeptical because my oil level always remains consistent, however there is a reason why I did this mod so I'm sure it'll keep my intake tract completely free of oil, I just don't think it'll be a lot of it.

Please do post some pics though I'd love to see how much oil your v6 accumulates in the catch can.

you know i'm hella skeptical about this. even after doing the home depot catch can. mainly because after so many years of driving (after i got my TB bored; it was honed and had a new butterfly made. when i got it back it was spotless) my TB hasn't gotten one bit of carbon build up, nor has it gotten any dirtier (i check it every so often just as a routine check along with oil, air filter, etc.)


also, when i did have the home depot catch can it barely caught an ounce or two throughout a 6month period (at which time i said screw this and took it off)


(sorry about no grammar at all, too tired. been typing correctly all day)

Heres a fast snaps with my cell ill take better pics soon  of my V6 i drew a red line to show you where the oil level is at now


(http://img4.imageshack.us/img4/2093/oil.jpg) (http://img4.imageshack.us/img4/2093/oil.jpg)

thanks cna, that's a good bit of oil, what period of time did this accumulate over? and what driving conditions?

I still don't understand the point of this....what does this do for you?

reduces the amount of oil that is thrown back from the head into the intake tract.

Google is your friend.  This is what was on a Scooby site, so keep in mind that it is geared towards turbo motors, but also applies to n/a motors.  I deleted all the sales bullshit from the actual information.

OIL CATCH CAN
Blow-by is a constant problem with any turbocharged engine. While a normal byproduct of the combustion process if it isn’t contained outside the engine it will collect and gum up the valve train, turbo and most importantly the intercooler and plumbing. When this occurs it reduces the thermal efficiency of the intercooler, thus losing power and performance.

Why do I need an Oil Catch Can?
Lets look at your engine for a moment.  Every engine during the normal combustion process, has blow-by.  Engine Blow-by is excess combustion gases that leak by the piston rings and escape into the engine crankcase. During each compression or power stroke of a normal engine cycle, a very small amount of gases leak by the piston rings. This happens because the piston rings do not create a perfect seal. This Blow-by of gases is very small, but the higher the RPM and the more pistons, the more the blow-by starts to create pressure in the crank.

This pressure needs to be released, and is done so by crank case vents. Because manufactures have to keep environmental issues in mind, these gases can’t just be vented to atmosphere. So the OEM’s vent these gases back to the intake system to be re-burned. This all sounds good, but Blow by is nasty stuff!

Engine blow-by contains gases and oil from the crankcase. The gases aren’t really a problem, but the oil is. This oily mess coats everything in its path as it makes it way back to the combustion chamber. This nasty oil mess gets into the turbo, then boost tubes, then intercooler, into the intake manifold, and finally back into the engine. As the oil creeps in between couplers and boost tubes, it can cause the connection pop off under boost.  This oil then gets into the intercooler coating all the cooling fins. This greatly effects the ability of the intercooler to cool, and the efficiency of it will drop! This will cause a huge loss in power and can cause detonation.  The last place this oily mess sees before the combustion chamber is the intake valves. Because of the temp differences and the oil impacting them, the oil will start to build up and form sludge. This adds up over time, and can cause many other problems, and hurt performance.

From this you can see, blow-by is bad, and it needs to be delt with.

How Does the Oil Catch can work?
As describe above the oily mess goes from the crank case to the intake system, and generally through a rubber hose.  An oil catch can simply intersects the hose and the oily mess before it reaches the intake system.  The top of our Oil Catch Can has 2 fittings, one in and one out. The oily mess goes in the can, gets trapped because of either the media inside the can, or from the change in direction, or from a change in temp.  This separated the good from the bad, and collects the bad.

As the fluid fills the can, the end user can use the sight tube on the side of the can to determine when to drain it.

Why would I need more than one Catch Can?

Because engines have more than one crank case vent, and or more than one type of crank case vent, they can use more than one catch can. For instance on a Subaru WRX, there is a crank case vent, valve cover vent and PCV hose.  All of these vents do different things at different states of engine load, and in turn, all could use a separate catch can.

Word tim.  Thanks for learning me. =)

where did you order this from ?
found one that looks similiar but for 59.99

so how is this thing holding up? when i got my TSX IM the runners were all black and gross looking so this may be in line for me.

haha you want an honest answer?

I do.  Tell us the truth.

I'd also want to know.

3k and not a drop. Makes me wander where the PCV valve vents to. Cause I have to be missing something.

yeah, to be honest, my breather filter( matt i know you hate it) isnt oily at all from the crankcase. I dont think its changed colors for about 3.5k

seth you really need a catch can with that filter arent you just blowing oil all over your engine bay?

So I see that you used the pcv tube for the oil return...  There's some issues that come with doing that, but at the same time I'm not exactly sure if our engines have a second means of releasing trapped air inside the crankcase. If someone can elaborate, that would be nice.

pcv tube for the oil return? issues with the tubing? elaborate.

As far as I know the PCV [positive crankcase ventilation] valve is responsible for the second means of blow by release. However I don't know where it actually vents to.

Sorry... I was wondering where the built up pressure within the crankcase would vent to since you took the breather tube and hooked it up to the oil catch can. That breather tube normally goes to the intake tube where the built up air would be sucked up and recycled. Without that, I imagine that the air pressure would just build up inside of the crank case and the weakest part would break (probably some of the tubing on the oil catch can or the fittings on it). Maybe it's just me, but I don't think there's a second means of blow by release within the crankcase in our engines.

Edit: Now, I see something that I didn't notice before. You know that tube that's on your intake? (The one between the maf sensor and the TB)  Where does that go to?  That's the tube that's supposed to go to the breather tube that's on the valve cover. Maybe I'm wrong and there is a second means of letting air escape from the crankcase. Time to go investigate!

No, i cant even tell you how long I've had it with no problems. or even a trace of an oil spray. even on the flame retardant hood thing. where its usually evident (esp on turbo cars)

but as to stirfriedferret. If you're saying he has no vacuum pulling pressure out, he does; the tube goes from the crankcase to the catch can which then goes to the intake. so the intake is pulling the clean air out of the catch can keeping a vacuum.

Ah, alright. Thanks, Seth. You answered my question

hell i may end up doing this..but i may put the catch can closer to the PCV opening. just in case the amount of tubing has an effect or something.

but i'll need to see if it actually catches anything. if it doesn't then im not doing it. another reason why you may not see the oil that is being caught is there needs to be a significant amount of oil in that can to actually show on the side thing. just a thought.

unscrewed the bottom and no oil. Amount of tubing doesn't play a role since the walls are reinforced and the motor doesn't produve enough vacuum for it to collapse.

oh i see. oh well lol maybe, maybe not.

Okay, I finally looked at the pictures a little closer this time and read through everything.  The reason why you're not getting any oil, is because you have this connected to the breather port on your valve cover.  Oil catch cans are to be used with your PCV (Positive Crankcase Ventilation) valve.  That is located on the front of your engine block, by your water pump.  I'm getting a catch can soon, so I'll take some pictures to show you where it should be connected to.

Yeah, maybe you could get some better pictures (no offense), but the ones in the OP were way too dark. Maybe it's my monitor, lol.

I've already posted this on Gen7A

I believe the above catch can setup is wrong.
Because in the above setup he connects the breather hose to something else, from what I thought in a catch can setup, you are supposed to have a catch can in between the PCV and the Intake Manifold. Correct me if I'm wrong.

My setup
http://img24.imageshack.us/img24/9636/dscn2087n.jpg (http://img24.imageshack.us/img24/9636/dscn2087n.jpg)

That's how I have my catch can set up.  Fuck, I have the same fucking catch can as you too.  Can you show me a better picture of the mount for yours?  

After more research, I've found that you can use a catch can with your PCV and valve cover ventilation.  Both set ups are technically right.  I'm going to get another catch can to run another one to my valve cover ventilation port.

well basically it's a bolt that holds the radiator onto the chassi, I just got the two metal mounts that they supply you with and bolted them together to form an "U" shape and then just unbolted the radiator bolt and placed the new joined mount onto where the radiator bolt goes and rebolted the radiator, and then just placed my clamp on the catchcan and tightened it on the mount with the curve side.

(http://img18.imageshack.us/img18/6497/dscn2097.jpg)

Thanks for the picture man.  I have mine in a different location, but I will probably be using that for the valve cover ventilation when I get a 2nd catch can.

but i'm confused, how does that valve cover port relieve crankcase pressure when it's located on the head.

It doesn't, but the valve cover opening is for pressure that could build up in the valve cover.  There's a port there for a reason, and since you can vent oil out of that also, it's worth considering that for a catch can too.

I have 2 of thouse catch cans same red and all you can have one if u liKe.

Yeah man.  I'm into that.  If you see Piero before he comes up to RI this weekend, you could give it to him.  If not, I can give you my address and I'll paypal you money for the shipping.

Iight no problem

I got you Tim...   I'm meeting up with Clemente after he gets out from work tomorrow morning.

Badass.  Thanks guys!  Let's try to keep this thread on topic now.  I will be installing a 2nd catch can as soon as I have time to.

yea i used it for a while but with the v6 i dont have as much space as you i4 guys so i had to give it up at the moment i made a custom one out of a water/air separator just waiting for a sunny day to install it

Sorry for posting from the grave, but what are everyone's thoughts on those $20 eBay catch can? I know you get what you pay for, but if the hoses suck i can just get some from home depot. It's mainly the can itself that I'm worried about. If they're really that bad, I'll just stick with OBX.

I have one of the "el cheapo" eBay ones and it's okay.  I got the hoses from Auto Zone since they would be able to supply something that's going to be able to withstand the heat and the oil better than the shitty hoses they give you with the catch can and what you can get at Home Depot.

Are you able to stuff anything inside the cans, or are they pretty much closed off? I'm really tempted to get one of these catch cans after seeing the shit in my injector base. The runners were like black. After I get a catch can installed, I think I'm going to do a cleanup of my car. Clean the blow-by in the TB and IM, clean the MAF, etc.

You can't "stuff" anything in them.  If you can justify spending the money, go ahead and get one.

Alright, thanks Tim. I was thinking of using the stainless steel scrub things to put in the can, but it's no big deal. Better than nothing. I can't wait to do this.

so both of these setups are correct(the first one and http://img24.imageshack.us/img24/9636/dscn2087n.jpg)? which one should i do cause i just got this same catch can and was going to install it for the intake side?

I believe the one that goes into the intake manifold is "more correct" because the majority of the blow-by goes through there. In other words, you're going to catch more oil on that setup rather than the other one on the intake side.

alright that's what I figured..thanks....wish it wasn't snowing so i could install this

Had a nice long weekend with the K24

Installed Hondata Heatshield Gasket , P2R intake manifold gasket, painted my intake manifold, and installed my OBX oil catch can.....  (intake manifold position)

Installation is a breeze, mounting the catch can is a little tricky, i protected my one hose and attached it to that.... the can sorta sits perfect in that little area near the radiator.... doesnt move at all
tubing was a breeze, just a few hose clamps (which i plan to clean up) and it worked out great

10-15 miles on it so far and my bottom tube is already brown (showing signs of oil vapors being caught)
as you can see behind my injector plate area was pretty oily and dirty, runners were oily, injector runners were oily.... so hopefully the catch can will cut down on this issue
