DIY: Oil Catch Can for Rogue

[UR2EZ]

This is a safe and proven mod that has been used on hundreds of G 35 over the past 7 years without ever a single problem All I did was take the same mod and I found the hose connections for the rogue. Followed this thread awhile back for my G35, and just recently built one for me Rogue, i will show you where the connections are...

Basically, this thread will show you how to go to Home Depot, go to the air compressor tools section, and get the Husky air compressor in-line filter. Also pick up two 1/4 inch brass fittings, one straight and the other 90 degrees (or both straight is ok). then go pick up a couple hose clamps for them, big enough to fit your thumb. You also need a rubber plug where the width of your pinkie tip is the middle of the plug, (i think 1/4 inch).
take out the innards of the filter, and just replace the circular, p0ker chip lookin piece, with the screw. Identify the in and out holes, and you will use a vice grip, a crescent wrench and some teflon tape to screw the fittings in. use a big a** alan wrench and vice grips to unscrew the valve at the bottom of the bottle, and replace with the rubber plug. (the valve leaks terribly, catch can will NOT WORK with the valve in place) Goto autozone or oreilly, wherever, and ask for this piece, i think they call it emission hose.



(on my g35 i managed to find hose at NAPA called transmission fluid return line.. since then i have tried every hose at autozone, oreilly, and napa, and have not had luck finding hose that doesn't collapse under vaccum and heat. The emission hose piece works and it's cheap.)

now go to your engine bay and rig it up like this:

OEM hose goes from valve cover to IN hole on catch can, don't forget hose clamps before you connect the hose.



Your emission hose goes from OUT, to intake thing that looks like a blimp:


it's the middle hose, the one beneath the other two, that has the obviously different hose clamp on it.

voila! here is your completed catch can
mine is almost full after only 4 months

Didn't know what this was and got this answer from answers.com

An oil catch can is used in turbo applications, or high-performance race applications where excessive blow-by (leakage past the piston rings) of air and fuel vapor occurs. This creates a positive pressure in the crankcase. Engine manufactures have placed a valve on the engine block which releases this pressure. This valve is known as a PCV (Positive Crankcase Ventilation) valve. During engine operation, blow-by gases, as well as oil mist from the rotating components of the engine, pass through the PCV valve and are routed back into the intake for the engine to burn off. However, some of the oil mist and other products settle along the engine intake and over time form a "gunk." The oil catch can collects the oil mist and condenses the fuel vapors while allowing "cleaner" gases to be passed back into the intake. Typically the blow-by gasses are passed through a wire mesh, which give the vapor droplets something to adhere to. Since the oil catch cans condense the vapor portion of the gasses, they will need to be drained periodically of all the oil, fuel and other contaminants.

So is this only needed in turbo's or will our Rogue benefit from this?

[Towncivilian]

Any vehicle will benefit from a catch can, since typically blow-by gases are routed back into the intake. These gases condense and can pool in the intake manifold, or at the very least coat the throttle body and the rest of the intake with gunk over time. A catch can is always a good idea, just make sure to check it frequently and empty it when required.

1. I am looking forward for ImStricken's input on this subject. He is probably in the Kia dealer right now, looking for a new Sorento for Mrs. ImStricken
2. I like the "look" of the engine on the G35 forum, but on Rogue, it looks crappy. I mean it looks like a cheap repair.
3. I think as long as my car is under warranty, I can't install such a thing in my engine
4. I honestly didn't understand which pipe goes to where?

[UR2EZ]

This is not a cosmetic mod. The catch can "catches" oil that would otherwise go into your intake, which, i don't have to tell you, is not good. Just look at how much oil would otherwise be going toward the eventual fouling of my spark plugs, or coating the intake manifold, and making poor combustion with all that vapor mixed in.
And no, not just for turbo, as you can see my rogue is catching plenty. This is my favortite mod on my G, even though it's among the cheapest, simply because you can see it working every time you open the hood. I will make some red circles on those pics above to clarify where the connections go, but honestly this is one of the easiest mods you can do, easier than debadging!!!

To better explain, what we are doing is taking the hose that goes from PCV valve to the intake, and installing a bottle in the line to catch the condensed vapor that is passing through.
Most of this mod is just adjusting the bottle so it doens't leak, and so it catches more vapor (some people put steel wool in the can to make condensation easier, but i don't because it can have little pieces i'm afraid will gewt sucked through).
The actual installation should only take 10 mins or so.

[Towncivilian]

I wish installation of a catch can was this easy on my Pathfinder! The PCV valve and hose is buried under the lower intake manifold.

[darylzero]

Thanks Towncivilian for the input (long time no see) and UR2EZ for the write up!

Qashqai, I think you mean ImStricken is at the Hyundai dealer At least the SanteFe is the last car I saw him talking about.

So is the only reason manufacturers don't include these in cars because they wouldn't trust everyone to check it every so often?

[ImStricken06]

what the PCV (positive crankcase ventilation) does is, it allows the exhaust gases (and emissions) that "blow by" or past the pistons to be recirculated back into the air intake stream. If not for a PCV setup, those gases would be vented to atmosphere. <-- and we know how the EPA hates that. I could care less about PCV, but the government and the EPA care greatly!!!

what they designed is to recirculate the oily misty air into our intake system. as we know that gums up AIT sensors, dirties up our intakes, gums up our throttle body, etc.

[UR2EZ]

I would like a bigger bottle, but the stiff hoses make it difficult to fit any can that is taller. Its really not bad, needs to be emptied about 5 months or every extended oils change interval

[ImStricken06]

you can simply buy a new 10 foot hose at any auto parts store, and cut it in half, thus being able to relocate the catch can. the problem i see is as engines wear, the piston rings wear, thus allowing more and more BBG(blow by gasses) to escape the combustion chamber that ends up in our intake system. i remember in my 2002 maxima gle (3.5 v6) after 120,000 miles it was eating oil like a mofo. it ended up destroying my air in take temp sensor.(because when our engine shuts off, the blow-by gasses still evaporate into the air intake system, and since the engine is no longer sucking in the air, the air goes backwards and out the intake system through the air filter(hence why our filters are dirty & greasy on the INSIDE, towards the end of their life)see oily spot on the filter pic below

[UR2EZ]

I would LOVE to find hose at an auto parts store that does not collapse once it gets hot in the engine bay with the vacuum, but I have tried every hose from autozone and O'Reillys to no avail. As I mentioned in the original post I once found sufficient hoes at Napa and not since then. If you can pinch the hose closed with all your might it is too soft

[Qashqai]

So do you think we should install one? Is is an additional precaution or a must? I am planning to keep this car for a looong time, so I want to take good care of it. It has 26.000 km do you thnik the intake is already contaminated?

An ImStricken, the product that you mentioned in your post is for single use I guess? The can looks single piece, so I guess you can't empty the oil.

Can we use such a thnig if we are using synthetic oil?

sorry guys, iv been kinda busy this weekend with random things to do with the Ms. lol plus making youtube video's now. i have had over 10,000 views on my couple videos i have made the last 4 days. (and all the hundreds of comments that have gone along with the views.)

put it this way, i have never had a catch can, and all my nissans have driven 150,000 miles plus without any engine issues.

is it a must? not at all. simply a precaution that is really intended for high revving engines. those with turbo's really need this. cars like Porsche's come with these already. race bikes too. yes they are reusable and drain-able.

is it a nice thing to have? sure.

is your intake already contaminated? yup. but wait, don't panic. that's an honest answer, but the true question should be: "is my intake contaminated to the point of needing cleaning?" - at your mileage i can almost guarantee that your intake and components are perfectly fine so no need to worry.

[UR2EZ]

Qash, This mod is not a precaution so much as a continuous filter for your cars breathing system. Doesn't matter what kind of oil you use and no this is not a 1 time use thing. The bottle fits in your engine bay and keeps oil from getting sucked in. Oil Can eventually foul your spark plugs early and make bad combustion. This mod makes your air combust cleaner thus more horsepower.... but not much. It's just regaining horsepower you have lost and saving your spark plugs from fouling. Even if you don't have iridium spark plugs , you are going to want to keep them very clean so that they burn all your fuel efficiently. In short, this mod is not necessary, but will prolong the life of your spark plugs and keep you from losing horsepower from Poor combustion

[Black B15]

Just thought I would add my two cents worth here.

I ran this oil catch can on my sentra from about 60K miles to when I sold it at over 150k miles. http://www.ebay.com/itm/200877755062?ss ... 1423.l2649. There were no issues what-so-ever and this thing would collect about a tablespoon of oil in there every couple of months. Now granted, the Sentra was driven HAAARD...at one point I was even running nitrous on the old girl...so I assume there may have been more oil than most cars would have collected in the catch can.

I plugged the bottom hole and ended up using transmission hose for the feed and return lines....which is high temp and doesn't crush as easy as you were mentioning UR2EZ...just a thought.

[UR2EZ]

Yes that transmission fluid return line is fantastic it's what I have on my g35 can... I just can't seem to find it anymore!

[TrevorK]

There were no issues what-so-ever and this thing would collect about a tablespoon of oil in there every couple of months. Now granted, the Sentra was driven HAAARD...at one point I was even running nitrous on the old girl...so I assume there may have been more oil than most cars would have collected in the catch can.

I wonder if the catch can is actually a useful thing for a typical everyday driver then? This amount of oil does not seem like much and I would wonder if it makes any sort of measurable difference in lifespan of components.

[UR2EZ]

of course, it's incredibly useful for a daily driven car. My G35 has had a catch can for about 4 years, and i've emptied about a gallon of oil from it in that time span.

[Black B15]

Agreed. It will help keep that funky stuff out of the intake manifold and throttle body. After 60K miles or so on the Sentra, which is right when I was installing the catch can, I had the throttle body off and looked in the intake manifold with a flashlight. It was easy to see that there was that oily funk everywhere in there.

I haven't done it to my Rogue yet, but all this talk is getting me thinking. I have had it for 9 or 10 months now and still haven't hit 7000 miles yet. Perhaps I should do the catch can before I get too many more miles on it.

[Qashqai]

I am seriously thinking of installing one to my Rogue.

I found the filter (http://www.canadiantire.ca/AST/browse/6 ... ?locale=en)

1. Filter: It is $28 +13%tax! wow! (In Canada, everything is expensive) I can justify the price in my mind, when I compare the price of an Oxygen sensor or other stuff that will be protected, however on the transparent container it says "avoid contact with synthetic oil". It says the container may fail if it is exposed to synthetic oil. My car has synthetic oil and it will "catch" synthetic oil in the future. So should I ignore this warning (written with big fonts) or look something else? I saw some catch cans on Ebay,but they are either too big (I prefer something small) or colored or made in China.

2. Hose: I found a hose as well. It is 1/4" fuel line hose. I pinched with my fingers and it collapsed with a really big force. It is rated up to 40 psi. I think this is for the positive pressure (blowing). What about sucking? If a hose rated for 40 psi will have a similar rating for vacuum? I have no idea.

3. Length: I think I am going to install the catch can next to the windshield washer reservoir. I will make a bracket and I have enough space to remove the bottle to empty it. However, what should be the maximum distance between the valve and the intake? Can I extend the length something like 6 feet (3 feetx2)?

4. Warranty: When I go to the dealer for an oil change and if the mechanics see the catch can, will it be red flagged? If until next year (when my warranty expires) something happened to the fuel system, will they use this against me?

[UR2EZ]

They won't care about your catch can when you do regular maintainance, but you should just remove it IF you ever have warranty work done, awhile back i was refused warranty work because of a can and it was annoying.
If you can pinch the hose closed, it's too soft. but it's not like your car will be ruined if the hose collapses, you will be fine. I drove for months before noticing my hose had gone soft (giggity) the first time. not a huge deal, and with most hoses you try, it's trial and error. Transmission fluid return line is ideal if you can find it

[Qashqai]

I see...so will the synthetic oil damages the can?

[ImStricken06]

I see...so will the synthetic oil damages the can?

yes. not only synth oil, but any petroleum product will melt plastic unless the plastic was designed to handle the oils/fuels. you gotta understand that the product that you found and the product that the OP was using is technically not designed for this. it was designed to filter the air for air-tools running off of a compressor.

will this void your warranty? nope. but if you come in with a warranty claim, and they find the catch can system had something to do with your claim = void.

[UR2EZ]

Don't be ridiculous, oil, no matter what kind of oil, will not damage the device I specified. The disclaimer is for use by morons, and as with all disclaimers, assumes the most negligent behaviors. This device has no record of melting or warping. Look at the link I posted in the first post, G35 drivers, hundreds of them, have been using the oil catch can with all kinds of oil, for several years and never had a problem. This is a proven device, If you want to see the success of this device just click the link I posted

[UR2EZ]

the catch can was an idea posted by a moderator 7 years ago! And yet in 7 years no 1 has ever had a can melt , or cause problems like that. honestly all of your questions can be answered by just clicking the link at the top of this thread, and reading through the hundreds of success stories. This is not a modification I made up for the rogue, It's a legitimate mod that g35 owners have been doing for almost a decade.

[TrevorK]

of course, it's incredibly useful for a daily driven car. My G35 has had a catch can for about 4 years, and i've emptied about a gallon of oil from it in that time span.

Then I guess your experience is different from the other poster who had "a tablespoon of oil every couple of months". To me, the tablespoon every couple months seems irrelevant in the large picture of things.

I personally find the whole concept of 1 litre/year to be odd. The dipstick on my Rogue indicates I use no oil between changes. Even accounting for the accuracy of the dipstick being poor if I am using 1 litre/year (as your claim) then I should see something on my dipstick as I'd be down 1/4 litre every 5000KM.

So I dug out some research on the matter and found quite a bit, but this thread really helps:
http://forums.corvetteforum.com/c6-tech ... ssary.html
http://forums.corvetteforum.com/c6-tech ... chcan.html
(Granted this is a maker of catch cans)

What it seems is that the harder you drive the car the more oil will collect. The easier you drive the car, the less oil will collect (to the point of being negligible). Therefore it would be safe to say that the usefulness of a catch can will depend on how you drive your vehicle. And installing a poorly designed catch can may actually cause problems rather than fix them.

While I'm not saying a properly installed catch can is a poor idea in all cases, because it is not, what I am saying is that for a vehicle such as a Nissan Rogue it may not be necessary when driven in a typical manner. I'm not sure about others but I'm sure not redlining my Nissan Rogue on anywhere near a regular basis (what's the point? It's a Rogue and still will not go fast). At least, that's what research has shown me based on opinions of people who have tried them out in a variety of circumstances.

I find too often people apply the same concepts they would to a high performance vehicle to a daily driver, like the Nissan Rogue where there is no noticeable payoff.

[UR2EZ]

Look how full mine is after about 4 months. And that is on a car that has only 30k miles, and has never seen redline, driven by an Asian girl who goes less than a mile per day. The Corvette forum you linked is about a car drastically different. Any oil going in the intake is bad, not just large amounts, and after several years, it adds up

[ImStricken06]

Don't be ridiculous, oil, no matter what kind of oil, will not damage the device.

calm down high-speed. oil is a petroleum product, which melts plastic. have you ever tried to put gasoline in a plastic cup? it melts instantly.
it takes a certain type of plastic to not melt/breakdown when used with petroleum products. if Sqash found a filter product that clearly states not to use with synthetic oils, then im going to tend to side with the manufacturer over you. hell, some car oils eat up copper - let alone plastics. there is a reason why manual transmissions cant use GL5(gear lube5) = because gl5 oil eats copper. and if your transmission has copper part's = say goodbye.
you are always to follow instructions from the manufacturers. they know the materials they use, and what chemicals can cause their products to degrade.

Look at the link I posted in the first post, G35 drivers, hundreds of them, have been using the oil catch can with all kinds of oil, for several years and never had a problem.

i could care less about the links you posted. im not disputing that 'oil catch cans' are a good idea. im simply telling you that not all pneumatic air filters are built the same. personally, i wouldn't even use a pneumatic air filter system in my car, as i feel it could restrict air-flow. I'm sure if you did the research and found one that met the flow/pressure specs of a cars PCV system then it would work fine. Just buying one at at random might not be the most practical idea. hence why i stand behind the larger cans. These are made to operate under a window of pressure and flow condition, without knowing the part, or the car's, flow and pressure conditions it's just a guess as to how efficient this thing is. Obviously it's doing something.
and if you have not noticed a thing about be, notice this: i dont care who/where uses what. there are hundreds of forums filled with dumb-asses that copy one another. hell, i had it out with a car-shop owner on 'another forum' about his ubber-cool "rust-module". he swore by it, while i kept telling him its a piece of garbage thats a total waste of time/money.

This is a proven device, and there is no danger, and no possibility of melting or damaging the can regardless of what kind of oil. If you want to see the success of this device just click the link I posted

again, maybe YOUR device is made to withstand oils, or synthetic oils. but the one Sqash posted clearly stated that it should NOT come in contact with Synth-Oil.

the catch can was an idea posted by a moderator 7 years ago! And yet in 7 years no 1 has ever had a can melt , or cause problems like that.

again, this isnt a concern regarding all "catch cans". this is a concern regarding the specific item Sqash was inquiring about.


READ THE RED LABEL, TOUGH GUY.

[UR2EZ]

Stop being so pedantic! If you read my comments I said "the catch can", so I'm obviously not making a sweeping statement about catch cans but only the 1 specific 1 I listed as being usable and proven. Obviously if people have been using this same exact product for nearly a decade and never had any problems with melting, then it is obviously not an issue! Duh Petroleum products can melt cheap plastics but what do you think bottles of oil are made of? All air filters even the husky brand say not to use oil in them and yet the oil has never had an adverse effect! If you really want to argue against it go to the g35 forum and argue against the hundreds of people who have used it without a problem ever! The bottom line is that it works fine and is not dangerous

[ImStricken06]

Duh Petroleum products can melt cheap plastics but what do you think bottles of oil are made of? All air filters even the husky brand say not to use oil in them and yet the oil has never had an adverse effect!

as i stated before, but you obviously missed it: "it takes a certain type of plastic to not melt/breakdown when used with petroleum products."

listen, you do what you want. and so can all the "catch can fan boy's". but dont think coming on here and spreading nonsense(that all plastics are the same, and to ignore warnings- just because others did it), you wont be stopped. NICOclub.com is full of very knowledgeable staff that will call out 'fan boy's' on their comments. AS I STATED BEFORE: I LIKE CATCH-CANS. BUT I I WILL NOT AGREE WITH PEOPLE USING PNEUMATIC SYSTEMS THAT CLAIM TO STAY AWAY FROM OILS.
