How to MS3 Catch Can Install with tons of pics.

[dadasracecar]

My understanding is that one of the downsides of DI motors is that they typically leak fuel down the sides of the cylinder walls. My CC contents smell of fuel and are very light viscosity. I've even heard the BMWs have an additional injection during the cycle for cooling purposes, though I've never been able to find proof.

Incidentally Pennzoil Platinum has excellent resistance to sheer from fuel dilution which is why it performs better in UOAs than M1.

The easy way to test if the WOT Box is responsible or not is to drain the catch can, turn off the WOT Box, run the car for a few weeks and see if you still get fuel in the catch can.... Keep us posted.

it's not the WOT box

the EGR and PCV contribute to the intake mani contamination issues
delete EGR plus
run an OCC between your PCV and intake mani + add an extra OEM PCV to prevent crankcase pressurization & you are golden.

Is there a writeup for the EGR delete?

You need a blockoff plate from Whoosh to do it.. Send him a PM.

Is it as simple as just blocking it off...? Does it create a CEL...?
Any adverse effects?

[Fobio]

yeah...I'm getting my RPMC inlet and an OCC installed and was wondering if I should do the EGR delete at the same time...TIA for info!

[4thStroke]

I would like to know more about the EGR delete and reasons why it should be deleted and whether or not its going throw a CEL.

OCC install will be this weekend for me with the CP-e FMIC, just got my Saikou Michi OCC today.

[JimmyMac]

Update, It's been awhile since I dumped out my OCC. But since I was installing my PG manifold, I thought I'd check up on and empty out the OCC. The clear hose has held up. Still soft. Not hardening or cracking. But I'll replace it when I get off my lazy butt. Same results as before. Just more of it. The gas stuff smells like crown royal or some crap like that. The black hose however is getting really soft. As stated in the other threads, do not use heater hose. Gotta find some better stuff. I'm sure this hose is collapsing under vacuum.

[AutoXRacer]

What are the two fluids?

[bova]

well probably oil and gas

[LBV]

The clear hose has held up

That's the exact same hose that came with my greddy catchcan. It's damn impossible to pinch by hand so i think greddy knows it'll work.

[JimmyMac]

Well the first pic shows what came out first. Obviously density/layers and all that scientific stuff. After the "crown royal" came out of the OCC, then the milky stuff started to ooozzz out. Some of that oil/gunk milky stuff was in the OCC feed line. Backed up alittle bit because I haven't emptied it out in awhile. Maybe I should start my own OCC moonshine business!!

[pbblaster]

This is probably a dumb question but here goes anyway. Why is a second PCV valve needed? I looked as a couple installation instructions from OCC makers and they did not use a 2nd one. Is it a problem if the CC gets manifold pressure? Can the CC be installed between the valve cover port and the PCV valve?

[AutoXRacer]

Quick answer is that you don't want to expose the CC to boost pressures.

[MattJackson86]

Is regular heater hose the best thing for the catch can or is there something else out there? Would a silicone heater hose be better? I just need to buy some for my install and want to use the right stuff so I dont have to come back and replace the hose at a later date.

[JimmyMac]

Regular heater hose will soften up over a course of about 2 months. Then it would just collapse whenever the hose was in vacuum. Try a hose meant for oil. It will hold up a lot better. The clear braided hose I bought from Lowes in the pics actually holds up a lot better than heater hose. But many would recommend something better that is meant for oil or fuel.

Yea I have been looking. I have found hose meant for oil, but it is not vacuum rated. its hard to get both...

Hows this oil hose: http://hosecraftusa.com/model.php?id=223 ?

[martin_nj]

are teh $10 catch cans off ebay ok? i don't see why you'd need to spend 90 bucks on a metal can...?

[booya620]

you definitely want to spend the money on a baffled can, I haven't ever seen inside an ebay catch can, but I bet that it isn't baffled. This means that oil may not stay in the can and recirculate into the system

[martin_nj]

there is no way that i can think of for oil to return into the system - please explain what you mean?

only cons i can think of are the adapter diameters....

[booya620]

The baffles condense the oil vapor in the can, the oil drips to the bottom and it does not go through to your intake.by including a baffle material, the vapor will tend to collect into a liquid form, otherwise it will enter the catch can freely and exit back into the intake which is not desired. The baffle will impede the flow of the vapor, allowing the oil to collect on its surface. But during this process, the vapor gives up a lot of its heat to the (metal) baffle, which makes the collection/condensation more efficient.

Yes, simple gravity will catch some blow by, but that also means that a whole lot more vapor is going in and out freely. you could alway get a cheapo and modify it. (found this info on evo .net)

great write-up!

were does that shit go when u dont have acatch can, you engine suck it up and burn it off?

[86AmishMs3]

wow, thanks. tons of pictures and info. Be good for when i decide to get a cc

[Lincoln]

I used this write up to install my Elite Engineering CC. Thank you very much!
I have to empty my CC every time I fill up with gas. It has made my car so much smoother.
I am running heater hose that needs to be replaced. Is this hose that was mentioned above suitable? General Purpose Industrial Hose
I am also VERY interested in the EGR delete. Is there a write up?

[cortytx8]

These are some ballin instructions, I'll be look here whenever I purchase a OCC

[Jessed87]

Yeah nice write up! I used the same clear hose and it seems to be doing okay so far...

[JerseySpeed]

Thanks all involved with this write up.
I also have the saikou michi catch can and will be installing it when motor is finished being forged.

[uoftguy]

I have a couple of questions regarding Catch Cans for those who have them and know a thing or two about them:

(1) Do you need a catch can if you're car is stock?
I only have a COBB SRI right and may or may not install a Turbosmart BPV (direct OEM replacement) in the future.

(2) Is it important to locate the OCC down low? It seems as though most people are putting it in behind the bumper where it will be a pain to drain (...put car on ramps...remove splash cover...etc, etc.). I'm sure there's a logical reason, I'm just not technically inclined enough to figure it out.

If I disconnect the 5/8" hose connected to the intake manifold and find that the inside of the hose is bone dry (no oil), would you still recommend that I get an OCC?

Thanks!

I think the short answer is yes you need the OCC, but read this too:

[RUMBLEFISH]

Has anyone ever installed a occ and the turbo stopped smoking afterwards?

[viper117630]

really nice write up, planning on doing this soon.

[Addikted To Boost]

mine actually didnt smoke before my catch can but after i installed the catch can and seafoamed it and took out my resonators it smokes like once every couple months now. Mines an 09, I think we are just doomed with smoking cars because our pcv system sucks. Mine only smokes when the front end is sitting lower than the backend (ie downhill) weird if you ask me.

[Oakes Salancy]

What a write up, and nice install.

[DISITRB]

FYI for any one you can find vacuum resistant hose on Mcmaster.com. p#5282K65 this hose is the one I used and works great. It can resist 14.5 psi of vaccum. that's 4x more the heater hose. Same hose used on Cobb's service bulletin just different color. I ordered black.

[senor blanco ms3]

just throwing this out there but would it be possible to connect a hose from the bottom of the OCC leaving the wing nut open and putting it through the bottom of the wheel well liner attached to another wing nut so that when you want to drain the occ all you have to do is reach under the car and turn the wing nut?

[cld12pk2go]

Very nicely done.

[trickytwelveinch]

Don't want to thread jack!

But I was browsing some forums and end ended up on the ozmpsclub (Ausies) mazda forums. Nevertheless, I found his pictures of his installation:






Too bad this setup is useless... so for anyone who is even thinking about doing something like this- you better check yourself.

[trickytwelveinch]

Oh, BTW, I dunno how or why some of you guys are actually getting liquid into your catch can.... I checked mine after installing it the first time about 3 weeks later or longer and the baby was all dried up....

I have lots of foam loaded into the catch can... which helps capture the tiny particles and any oil that gets in there, and that shit simply dries out due to the engine bays temperature.

I have the Perrin OCC which has a clear hose coming from top to bottom to show you that you're actually getting something inside of it.

I am currently working on shortening the hoses and mounting the OCC somewhere else.

[flyrevs2]

Where can I get some 5/8" vacuum resistant hose - I want to hook up my cc but can find any hose!!!! All the local auto parts stores dont have any. Thanks!
