i've been having a longstanding problem of oil consumption in my itr. i have clean plugs and it's not coming out of the exhaust and i could not figure out why until now. recently low-speed drivability has been poor because the throttle keeps sticking at low rpms and finally i brought it in to a&j. alan pulled the tb out and found it completely fouled with oily gunk. shining a light into the intake manifold inlet displayed similar results. after cleaning everything up and reinstall, the car ran much better. it was suggested that i should either run an oil catch can, or a filter. i tried the filter before, but all that did was spray oil all over the underside of the hood. as for the catch can... i can't find space to put it anywhere?

what do u guys do? and is blowing this much oil out of the breather hose normal?

 

One question I'd like to pose is what are the reasons for this happening?

 

i have my catch can near the brake booster, but my car is right hand drive and it fits perfectly with the adapter from CUSCO. not sure about left hand drive.
And for a lot of oil pissing, mine didnt do that because i can monitor it from the clear looking hose, it does a lil bit, but not as much as you describe.

 

Is this a result of oil getting past the rings? Oil blow-by maybe?

 

Most common place I've seen them installed is right down below the right side of the battery near the transmission. Endyn sells a kit using a modified Moroso can, and every fitting and line you need, and I think it's around $135.

just removed aem cai to install stock intake and throttle plate edge was lined with oil. Think i might invest a lil $$ to get myself a oil catch can soon!

 

Make that modified Moroso can......

 

Hehe you're right sorry

 

ITRbroham,no it is not the result of that.It is doing exactly what the pcv system is suppose to do.I spoke with some of the guys from King Motorsports at a race and they said the race cars use up to two quarts into the oil catch can in a 2 hour race.

 

Sounds like you have some extremely high crankcase pressure, Ben.

If I were in your shoes, maybe pull down your breather box and see how clogged it is. It's the little box on the back of the block. Be sure to install a new o-ring at the same time.

Yea, do the Moroso catch can. Make sure it is hooked up properly and you'll be in there. Here's my catch can installed...



See it on the pass.side strut tower?
Run a slash-tube extension on the OEM breather piece. From the back of the block, run a hose to the side of the can. From the top of the PCV, route the hosing under the intake and through the hole in the center of the manifold. Looks OEM and works nice.
BTW, mine was full of oil after 3 weeks. Works.

 

What do you do with the oil that ends up in the can?

 

Do u have turbo?? If u have turbo, then your cylinder walls have expanded and thatz the reason for all ur problems.

 

i know what you're talking about.... but no i'm not turbo.

the breather box. could it be that obvious? damn i never even thought of that...

the location of the can... will it interfere with a strut bar and/or aem?

the people i've asked about their catch cans said they dump the oil and do not reuse it.

 

Damn, I have this same problem. How much do those catch cans run anyways??? In CDN dollars please.

 

Hi Ben,

This is a common problem with Integras that seems to get worse with wear-and-tear and some aftermarket components. Large quantities of oil should not be flowing through the breather hose to the CAI. The flow should be in the opposite direction.

If the breather tube fitting on the CAI is close to 90 degrees to the CAI or worse, pointing away from the direction of the airflow through the CAI it creates a vacuum and oil is sucked into the CAI. Take a look at the OEM molded rubber hose and you will see how it is angled towards the incoming air.

I dont know how youe CAI is set up,but that could be part of the problem. I also ran a hose directly from the CAI fitting to the breather, elevating it as much as I could to avoid oil flow ehere I didnt want it.

Good luck with the Catch Can. Lots of information on the Endyn website on catch cans.

John

 

i don't understand this statement...

i don't understand this either... the fitting on the intake hose is still 90 degrees into the airflow, as shown in mike k's pic above.

how do i elevate it? i am running an aem.

Hey pooface, I drink it.

 

Ben, I don't run strut tower bar up front so I am not sure if it will interfere.
I have since switched from stock hose to AEM and it clears fine.

 

Look/feel the inside of the stock intake hose. The inside of the breather bung is angled slightly toward the incoming air. On the AEM, it is not.

 

Oil is not supposed to come out of your valve cover. It should come out of the PCV hose. Did you check that?

 

Mike, how did that "special built" motor come out? Never heard...

 

Here is a picture of my DIY oil catch can. It is mounted on the passenger side strut tower below the intake tube.



Also, here is a link to my webpage on how to install the DIY Oil Catch Can - http://www.geocities.com/bretq/DIY_O...tructions.html

 

Mike K, Bret Q.... How do you empty the catch can? Is there a drain on the bottom you can access or do you have to pull the thing out?

 

There is a drain on the bottom of the can which allows you to empty the oil. Here is a picture which shows Moroso catch can and you can see the drain.

 

Sorry man, you're gonna have to refresh my memory on that one. LOL. I have so many projects going on right now. Which one are you talking about?
Between my friends and I, the following projects are brewing...
* 85.0mm bore B20 w/ Endyn B18C head
* 84.5mm sleeved B18C1 block w/ JUN3 cams
* 86.0mm sleeved B18C1 block w/ Skunk2 cams
* 81.5mm B18C1 motor w/ 11.9:1 RollerWaves and JUN2 cams
* 86.0mm B16A w/ B17A crank, 13:1 CR and CTR cams

Yea, you could say we're busy in Naples right now. Heh..
