DIY Oil Catch Can for 94' - 01' Integra

[copymaster003]

Wow! This is a very good explanation of the theory behind the usage of a oil catch can along with detailed instructions! Anyone wanna make one with me?

You can go to my website at http://www.geocities.com/bretq/DIY_Oil_Catch_Can_instructions.html for information on assembling and installing an oil catch can. I used the Moroso because it contains baffling, which helps to seperate the oil droplets from the blow-by gases. Here is a diagram which shows how the baffling works.


DIY Oil Catch Can installation instructions

How to install an Oil Catch Can in a ’94 – ’01 Acura Intergra.


Here are the parts that are needed for the installation:


Moroso Dry Sump Breather Tank (Oil Catch Can). # 85470.
$65.99 @ Jegs

PCV Valve (real application is a Ford truck)
Fram FV294 or
Motorcraft EV-140 or
Puralotor PV-140 or
FOMOCO E7TZ-6A666-A
$1.99 @ Advance Auto Parts

Help! Ford PCV Valve rubber grommet #42048.
$4.99 @ Advance Auto Parts


Watts 3/8" I.D. Barb to MIP Adapter # A-294.
$1.48 @ Home Depot

Watts 3/8" Barb Splicer #A-290
$1.39 @ Home Depot

3/8" ID clear, high-pressure reinforced tubing (10 feet)
$5.25 @ Home Depot

Teflon Tape.
$.58 @ Home Depot

3/4" OD hose clamps. 6.
$1.50 @ Home Depot

Installation Instructions:

1. Put Teflon tape on threads of A-294 3/8" bard to MIP Adapter and screw into side of Moroso tank.

2. Install new PCV valve into Help! rubber grommet. Install rubber grommet with PCV valve onto top of oil catch can.

3. Locate a suitable location in the engine compartment for the mounting of the oil catch can. (I chose a location on the passenger side shock tower.)

4. Remove the hose from the original PCV valve barb. Install the barb splicer (A-290) into end of the hose and securing it with a hose clamp. Install one end of the high-pressure hose onto the other end of the barb splicer (A-290). Secure it with a hose clamp.

5. Determine the length of hose that is needed to the new PCV valve on top of the oil catch can. Cut hose the to length and install the hose onto the new PCV valve on the oil catch can. Secure it with hose clamp.

6. Install one end of the high-pressure hose onto the other end of the original PCV valve barb. Secure it with hose clamp.

7. Determine length of hose needed to install the hose onto the Watts 3/8" barb to MIP adapter (A-294) on the oil catch can. Cut the hose to length. Install onto barb on oil catch can, secure with a hose clamp.

8. Zip tie hoses securely.

9. Start engine and check to make sure there are no vacuum leaks.

hey guy! I sent you that picture before already... anyways... I'll build one with you. I'm just not sure which Catch Can I'm gonna use right now. trying hard to make my car looks STOCK! Cuz I don't wanna put up with BS from cops when I pop my hood.

[Hatchcrap]

hmm....sounds like an interesting project. im down, but funds are low, my car spits alot of oil from the valve cover breather. so that means i gotta make two catch cans? one for the pcv and breather.....

No, only 1 catch can. Theres a way to hookup the catch can to go

1) in between oil seperator and intake manifold
AND
2) in between the valve cover and intake tube

Thus this give you the LOOK of a stock system and you MIGHT NOT get a ticket for the breather on your valve cover. Also you can just create a slash cut inside your intake tube so that fresh air is rushed into the valve cover. YES, the valve cover breather is NOT to release oil vapor. That tube was put there to PUSH air INTO the valve cover. Just that your FI motor most likely sucks it back out. For NA people... don't bother with the valve cover stuff... its useless for you.

Remember this is just to LOOK legal, I'm pretty sure a catch can is illegal... especially a open system one (anything with a breather on it).

I'll try to find info on some guy that hooked up the valve cover/ intake part to a catch can and post it.

[hatchcrap]

cool! yeah i dont really want to run my valve cover breather back where the intake is on the turbo, the turbine is just gonna build up oil and make my IC all dirty. thanks ray

If you wanna go ALL POWER, the picture above is NOT the way to go. The picture above is trying to keep some of the aspects of factory evacution of the crankcase vapors. The Picture above just removes MORE oil but NOT all. It is however more legal if there is such a term. The setup below remove ALL Oil from the intake and you can probably run additional 2-3 psi of boost without detonation. Its a "open loop" system and releases vapors to the atmosphere. Its not gonna pass a smog visual. but you put the hoses right... it might still look legal. :)

[DOHC-LSR]

Also to keep positive pressure and to provide good ventilation of the crankcase adequately, the method below maybe better. Atleast it'll look LEGAL! :) You'll still need the Catch can on the otherside afterthe oil seperator.

yeah...i gotta dyno my car and get a new map sensor so i can up the boost. used to get detonation of some sort...but that was due to boost cutoff. i just wanna keep my oil vapors in check and get that IM clean of oil residue. btw smog is ok for me, everything under my engine is practically illegal....HAHA and i still pass with flying colors:D

How much boost you planning to run? :confused: Doesn't your MAP sensor read around 13psi? Guess you goin pass that huh? :D

[hatchcrap]

i believe the stock honda MAP sensor reads up to 11psi, but once u boost theres and addiction for more! i wanna run 1bar of boost on my weaksauce stock 180k motor.

btw ray, i need help, everytime i post or go to profile, i need to log in everytime. i tired to log in thru the main forum page at the bottom where it says "...cookies..." or something, but that doesnt seem to help. i dunno

yeaaaa......

[fume711]

Sorry Ray, this is not a riceboy mod... this is a performance mod... most riceboys wouldn't build one of these catch cans and don't even really understand what and where it goes or how it does what it does.... they just get a valve cover breather and think they have done something major... like James and that HelluvaFast SI! j/p oh, this is Ray C. Al didn't log out...

[cowboy]

yes, i understand that the catch can is not a riceboy mod but....

when it would be time (or appropiate) to use that jpeg, i may forget about this picture, so yes, i had to use it....

it's just for a few chuckles...

ray, chuckling

[DOHC-LSR]

Yeah, that Altezza one is still the tightest tho. I wonder how many of these pictures are out there? haha

[DOHC-LSR]

Danny, you doing a catch can soon? Wassup with the ITR Swaybar too?

[DOHC-LSR]

hey guy... fawk that BSQ catch can... here the ultra ghetto way I'm gonna go...

DIY PVC Plastic catch can (http://www.y8s.com/celica/air-oil/)

[DOHC-LSR]

somehow it looks decent and totally customizable in size and something I'm familiar working with PVC pipe!

[copymaster003]

Whenever guy! I'm down... just haven't had time to order the parts. Let me know when you wanna do it.... And DAMN, that PVC DIY Oil Catch Can look tight!, Andy put his in yesterday, nice and shiny! Gonna do header, high flow cat, and exhaust at the same time, so let me know when! Need to order parts!

[DOHC-LSR]

I'm pretty sure I'll be doing the PVC catch can. Parts from OSH... As for the R swaybar... I'll probably get that later... maybe Dec? or Jan? with Christmas and finals and $$$->Christmas...

[DOHC-LSR]

Header, high flow cat, and exhaust is probably gonna take you the whole day... you mean the same weekend? I don't think you're gonna do the R Swaybar the same day right? + the catch can? more of a weekend if not 3 day thing with all that.

How did the catch can install go Andy? Did you put baffle inside the can?

[andyl8u]

The install went great but I didn't put in baffle in there. I think I should later on. My engine doesn't shake as much after I drove like 10 miles. I think it really helped my engine.

[DOHC-LSR]

Well we started building them. Me and Danny that is... hopefully by this weekend it'll be done and final cost will ve <$40.

[copymaster003]

Yes, we have started to build the can's that catch, mostly due to Ray C. ingeniuity. Thanks Ray, let me know how muchy everything cost(s)? And, take some pic's, I know you borrowed Andy's camera. Either that or take pictures of yourself and post them!

Daniel (the one who was getting high off Epoxy while making these magical can's that like to catch)

[DOHC-LSR]

Well, I think I've bought MOST/ALL the parts needed for the catch can now. The total cost each so far is

$42.35

This includes the cost of a drill bit I didn't need to buy and several feet of the WRONG sized hose. So that means anyone else building this should be able to do it CHEAPER than what I said/did. The only thing left to buy is probably some wire loom to cover the clear hoses (this could have been avoided if we had bought black fuel hose) also this is not even neccessary, I just don't wanna see the catch can system. And lastly a bracket of some sort need to be made/bought.

[OneBoredBew]

hey guy! hook me up with the parts i wanna make one cuz it looks kool. hehe. but yea i wanna make one dont feel like pay 99 bux for like an greddy one or something like that.

Well so far the can follows these 2 DIY combined with some more modifications.

http://www.y8s.com/celica/air-oil/

and also the first picture signed by T.O.O. in this post.

I'll show some pics of the parts and where I got them when this is all done and also let you know where my mistakes were made.

[DOHC-LSR]

Andy, can you e-mail me the pics I had taken with your camera? Also, Danny... I think I figured out how to make the mounting bracket and I'm gonna buy those last parts today. The bracket is whats been holding me up on finishing the catch can install. I think after you get this in, probably this weekend your idle problems will be gone. :happy: Otherwise, it will be super bad news and it could possibly be the ring lands. :sad:

[DOHC-LSR]

heres some ghetto pics of the "can".

[DOHC-LSR]

inside the cap, this rubber gromet needed to be siliconed to keep a air tight seal.

[DOHC-LSR]

and if people want these same parts... only Danny has installed it so far and I'm planning for this weekend. If Danny can get some pics of the engine bay install. I'm still deciding where to put mine... as that will dictate the can size and I kinda want it big... but hidden at the same time... :idea: anywho... some this costs us like $40-$45 :doh: but thats including a stupid drill bit I already had! :bash: any who... this should be do-able for under $20, and that including that $6 drain valve!

[OneBoredBew]

damn hella hommade!! nice!!!:thumb_up:

[fume711]

yep haha

i think you should create a page labeled "home depot add ons to gain horsepower" or soemthing like that....so if peeps wanna make something..they can just refer to ur page haha and make ur site popular! hahaha
