There are many threads explaining the importance of an oil catch can (thank you OPs to the threads)
https://acurazine.com/forums/2g-cl-2001-2003-50/importance-oil-catch-can-717397/

In a nutshell, when the pcv and other vaccuum systems suck out the gases from the crankcase and dumps it into the intake to be burned off,
Oil might be sucked in as well.
The benefits of a catch can is to catch the oil so it doesnt get sucked in through the intake manifold and possibly contaminate or have build up inside, nor the oil wont burn through the exhaust.
This can result in a cleaner intake manifold.

Being cheap i bought the EBAY universal catch can for under 20 bones.
Functionality:9/10
price:10/10
build quality:7/10

Here is what it comes with from the TL side of the forums (thanks OP)
https://acurazine.com/forums/2g-tl-1999-2003-98/oil-catch-can-diy-693521/

first picture.

With my install, i only used the ring clamps the catch can and the felt gaskets and the blue tube.

The other parts are for mounting, but i couldn't figure out how to mount it with those.

Mounting is all custom, and you can use your own tubing and make it all custom but i'm cheap so i utilized the parts it came with

Here is my ebay catch can installed to the left of my G-take (ghetto intake)

Here is a diagram to where each hose goes


I have chose to mount it using the big clamp to wrap around the catch can
and a 3/8 hose clamp clamped to the strut brace/bar thing.

As you can see, one tube goes to back of the valve cover
and one goes into the pcv valve

***Before installing you might want to untighten the screws on top and add the gaskets included or RTV sealant for 100% sealingness so there will be no air leaks. Slap those things on then retighten (i believe it is a hex screw thing like H10, i'm not sure i forgot) Also tighten all other components as they might come loose.

Here is more pictures of where the hoses lead up to



Here is the PCV location (the bottom blue hose) (simply unhook the existing tubing and plug up the pcv with the blue hose)


Here is the location behind the left of the valve cover (next to the top most left bolt that holds on the plastic valve cover dressing engine thing VTEC black plastic)
Simply remove the tubing that is there as well and connect the other blue hose



Now simply connect the blue tubes to the catch can and tighten them down with the clamps, make sure the other ends are clamped down as well using the existing tubing clamps or by using the clamps off the other parts included with the ebay catch can that are not being used.

Then you mount it wherever you want.
If you use my method of clamping it down to the strut bar
make sure you cut the tubing precisely as there might not be enough tubing for both routes.

Enjoy cheap goodness for your engine!


Now being this is cheap, there are some drawbacks.
Here is a picture explaining why.
THe holes from the tubes are so close together than oil might be sucked back in by the other tube



There was an awesome post somewhere on here that i cannot find
or maybe it was on a hondatech or teamintegra forum i just can't find it but the guy cut it in half put a divider and jb welded it back together to ensure that the oil being caught didn't get sucked back into the intake

The best way i can explain it is this

You cut it in half, then add a metal divider of some sort in between the two holes, ensuring the oil drops down and not sucked into the other hole. Just JB weld everything back





Though this has been of concern, i have not visually seen oil into the other tubing so far. If i do see oil being sucked into the other blue tube (you can just see it changing color, the other tube should have some oil residue which indicates that oil is indeed being routed out into the can) i will open her up and do those changes. After about a week of driving with the catch can, there is already about 1oz of oil inside the can.


HoAp DIs Halps, and enjoy a cheap DIY project to improve the health of your car




Inappropirate smiley insertion:: band::ministe r:

 

Nicely done and informative. Thanks.

That being said, can a mod disable this guys emoti capabilities?

 

Holy shit your intake is fucking ugly.

 

Gonna have to buy a catch can now. Damn you OP

The TL DIY link you posted has the tubing connected to the front valve cover. Any difference?

 

Hey hey hey fuck you
J/k to each his own. being cheap has a price and that was the only color exhaust wrap i had laying around, i could go fancy and get carbon fiber sticker/vinyl material and wrap it but that = $$$

As for the front of the valve cover, i'm not too sure bro. Does the Tl have the non type s version?

I know for a fact that there are multiple locations you can install a oil catch can , i've seen people with 2 even, so it might be that the op of that thread installed it in a different location.
I only know the pcv valve location and behind the valve cover i'm sure there are more places you can install to have maximum oil catching skillz but i am not so sure as this was the easiest one i could think of

 

Noooooooo! I left a disclaimer stating that it was an inappropriate smiley insertion so it should be legal. If i didn't state a disclaimer then it should be illegal!

 

I routed mine differently, but I can't really explain right now because my skull feels like its going to implode after reading this

 

^^^lol

 

K I think I figured it out.

The intake pipe has a breather tube that goes to the FRONT valve cover. Air goes through there, and passes pressure through to the rear valve cover.

Then the REAR valve cover with the PCV valve sends that gas/oil mix directly into the intake manifold. You put a catch can there to filter out the oil, wohoo.

That catch can will stop most of the fluid. However, at wide open throttle the flow can reverse. This means that gas/oil will go from the FRONT valve cover into the intake. This is how the TB gets dirty (because the rear valve cover one directly puts the gas/oil into the IM, bypassing the TB).

So you have a catch can in the rear. To be extra clean, you can have one in the front. However, since we aren't Forced Induction or Direct Injection, either one should be more than enough.

 

Ok took an advil--head feels better..I ran mine between the front vc and rear pcv, and added a vent to the can since it didn't come with one

 

^This is a picture of the flow during normal use. However, during WOT the flow is reversed, which causes oil to go into the intake.

 

you need one on the front and one on the back skip or else its not really doing the job. which is why i got 2

 

This what i was thinking about, i thought it would be redundant but what Karanx7 explained i will be going with 2 as well. better to do the job right than half assed >

For the front Valve cover i believe it will be as simple as

front valve cover -> tubing -> oil catch can ->exit through other tube -> tube into intake

at least for j32a2's

 

oh yea its easy. mounting it i found was the hardest part. i didnt wanna ziptie it

 

I have a catch can for the rear cover and it catches a surprising amount of oil. I don't drive the car hard or anything. If you open your intake manifold up, there will be pools of motor oil inside.

 

yea its a bad design for sure, it just harbors oil in it and has no where to go

 

What negatives could happen with all the oil build up in the intake manifold?

 

Fouled plugs, coated pistons and valves, poor combustion. Carbon build up kills gas mileage as well as performance.

 

but most importantly it looks ugly when u pull the manifold apart!

 

I am just curious, hasn't there been tons of posts about DIY catch cans on this website already???

 

Probably. OP refers to one in the first post of this thread.

 

Yes turbo negro, i linked some of them in my opening post,

BUT

I haven't seen one specifically for the j32a2 engines more specifically for the 2001-2003 Acura Cl.
They were mostly for the TLs
or Non type s CL ( and TL)
j30? i believe

 

Coudlnt' say it better than civicdrvr and clsprogression 01

sludge build up causing decrease performance/ mpg

and your intake manifold will be all oily brown and possibly have carbon (black) deposits in it, imagine all that gunk blocking the flow of air!

 

Did you just call OperationDarkie "turbo negro"????

 

i will get a pic of my engine bay with both catch cans on my 01 cl-s to put a stop to all this madness.. and YALL gonna be jealous with my fully aluminium red annodized simota catch canz.... mmmhmmmmmmmmmm lol

will post it up monday hopefully.

 

Haha yeah, cause his registered member thing is "ultra negro"

and i just called him turbonegro cause it's a band

 

How much did you spend on a catch can

 

But the pipe routing should be identical for the 2G CL/TL regardless of engine.

 

lol it as like 80 each... i bought one.. and then thought to myself wtf are u doing u goof.. cause there are 2 sides to the motor.. and so i bought another.. so like 170s..

looks nice 1 and will keep motor wayyyy cleaner in my opinion 2..

still need to get that picture posted up gentlemen.. if u can believe it i do not have a camera not even one on my phone cause it's a sonim xp1300 or w/e and does not come with one..

so when i am around a friend who has camera i will get that pic

 

haha yeah does look fancy! I bet it isn't cheapo made like the ebay one, the holes are close together where the tubes enter and there isn't anything to divide it so it might be getting sucked back into the engine, so far i haven't notcied that though and there is some nice black oil inside

lol you driving a fancy CL and your phone don't have no camera

 

Looked different in the other forums because i think they used a different route of tubing i didn't understand, and also under the throttle body and the coolant tubes looked so different


I learn slowly but surely

 

Update: Oil residue is seen going through the other line -_-
cheap you get what you pay for..

but low and behold! I have a theoretical solution!

I will simply unbolt the top part and hot glue/ epoxy a slurpee straw (or whatever size will fit) into the hole that sucks in the oil, this will insure that the oil will drop down to the bottom, and not just get sucked into the other hole.

CHeap ftw

 

I would recommend a catch can to everyone even a N/A stock engine. You would be amazed at how much oil I removed from mine just after a few thousand miles.

Cheap ftl, you get what you pay for. Might as well make one from a coke can. Those blue hoses look awful too.

I made sure the one I bought was baffled, and it has steel wool mesh in it to help. It also has a drain tube at the bottom to easily remove the oil.

Most catch cans you can buy are not baffled, even the name brand expensive ones.

I also wanted one without a filter on it dispersing oil vapor all over my engine bay.

If you think $80 is a lot for a air/oil separator(catch can) then you will think mine is a ripoff. I paid nearly $150 for mine.

This was after 1200 miles.


Here is my universal moroso air/oil separator. I made the bracket myself by cutting 2 brackets down(oem bracket and moroso one) and welding them together.



You can't see the drain tube in the pics.

 

It's hard to tell from the pics. Just to be clear, this is an intermediary that sits between the PCV valve and wherever that tube leads?

 

Please don't

 

 

And the intake manifold.
Basically something that strains the oil from that air and collect it to be discarded.

 

pics will be up tonight or tomorrow, i got a camera on ME finally LOL... just been super busy with school, essays, work, partying... u KNOOOOO
