Catch cans: what are you running?
 

This thread is not for debating whether a catch can is needed. I know that they are, I have seen it with my own eyes. Installing a catch can will be the first thing I do when I get my car so we can save all that for another thread. The only question is which can to use. The catch can manufacturers that I am used to dealing with do not produce catch cans for smaller displacement engines. What are you guys using? Any feedback on Saikou Michi?

I would like one but I haven't found one. I used to have a Challenger and everybody ran the one from billet technology on those.

One is needed

This is RHD obviously.
No I don't have one.
Fitment looks good.
Around $260. USD
No, I don't know of a US vendor.
Basically just sharing pics:)

I am running Cusco catch can at the moment.

Is there anything inside that can or is it empty? It is just too flashy for me.

I am planning on running a Mishimoto. I have heard good things about them. Seem to be well priced.. good technology.. etc.

it's completely sealed so i don't know definitely but I think it's empty.

I have the Cusco. Paid around $130 for it. It won't arrive until this week though so I can't answer your other question

I ran a Saikou Michi on my MS3. It's very good and easy to drain with the bottom valve. It's about the size of a 20 oz coke bottle. It may not be all chrome and blingy, but it's well designed and does the job. Here's a How To that I did for the MS3. http://www.mazdaspeedforums.org/foru...ons-pics-7216/

I had a feeling that was the case.

The lack of bling is a good thing in my opinion. I prefer function over form. At this point there is a good chance I'll go with Saikou Michi.

Our customers are picking up the Mishimoto or Cusco Catch cans.

I am going to inquire about them making a BRZ version.

Crawford !!!

I have Cusco, it's just hollow can. I have it for for a while and don't see any trace of the oil yet. Will see after the track day.

I used the Crawford on my turbo Subaru and it is the best AoS/catch can but I think the Grimmspeed AoS is probably okay with the amount of blowby on a NA motor.

For the turbo guys, definitely Crawford. No reason to look elsewhere imho.

Correct the Cusco is hollow. The Mishimoto is baffled.

Catch cans are a pretty universal item though.

as someone said, if crawford makes one, that's the one to get...otherwise MOROSO is next in line for making a unit that actually WORKS.

the grimmspeed does nothing.

Yup

It's also designed for the BRZ/FRS

Is there a place to get a Crawford one?

Can someone explain the purpose of a catch can?

Basically it keeps oil from going into your intake and keeps it routed to the block. If you plan on doing auto-x or road course racing it is a good thing to get.

This one is universal but I would check to see if it's compatible anyways as I am just learning about car mechanics.

I saw that but was wondering the same thing.

yea the universal should work. it's pretty simple since it's an NA motor.

so where does one get the oil cap that lets the oil back out of can into the block?

In regard to how large the reservoir ought to be, how much oil are you users collecting with your driving habits?

Radium has been making some nice cans: https://radiumauto.com/index.php?p=p...id=28&parent=5

On the turbocharged Subaru motors there was a lot of "blow-by", with a lot of oil being fed back into the breather line. Which feeds into the inlet pipe, and thus got routed back into the piston area. I've taken top mounts intercoolers off of 2 year old cars and literally poured the oil out of it.

Now, other than it looking nasty, it also increased detonation on those motors. Presumably that could be an issue with these 12:1 compression motors, but nobody has the mileage to determine how much.

I've got a couple of different breather catch tanks we make (different brackets for different models) so I'll probably fit one up. There is not many (if any) FR-S/BRZ specific catch tanks at this point, probably just adapted ones from the Turbo Subaru or Evo models. The typical older gen Subaru has two breather lines that T into one to the inlet - the FRisBee twins just have a single line from pcv straight to inlet. So one of the inlet ports will need to be blocked off.

I would prefer something application specific as opposed to a universal one if any vendors are checking this thread...

Just want to get some clarity on this. I just received my Cusco Oil Catch. Is it actually functional or should I not open it and send back?

Paul, I would love to see a FRS/BRZ specific set up from you guys. Do your systems use any sort of baffling?

Paul will an Oil Catch come with the AVO turbo kit?

We do use baffling in the system, nothing too complicated - but then, catch cans are not complicated technology.

Crawford will have them...

I'll also carry them because they're badass

they are really badass pieces but i think $300+ for a oil catch can is a little to much when you can have pieces with the same quality and do the same work for a lot less...my 2 cents.

Um, yeah, if I'm going to spend money on oily cans with nipples attached, it sure as hell won't be what you guys are buying!

You might want to do some more research.

Need some education on these. So they help prevent oil from returning the motor via the breather tube? How do they function in conjunction with oil coolers? :thanks:

Modern engines feature a variety of emission control devices and systems to reduce the toxic gases released into the atmosphere. One of these is called the Positive Crankcase Ventilation (PCV) system. During the combustion process a small amount of gases leak or “blow-by” the piston rings and create a positive pressure in the crankcase. The PCV system vents these gases along with oil mist from the crankcase and routes it back into the intake manifold so it can be burned off. The problem is that over time the excess oil vapor collects along the inside of the intake tract and forms a “gunk”. This can lead to a variety of issues including carbon build up, retarded timing, detonation, and decreased performance.

A catch can or air-oil separator is a device that will condense and collect the oil vapor before it has a chance to reach the intake system. As the gases and oil vapor enter the can they typically pass through a screening mechanism that gives the oil vapor something to condense against. As the droplets form they drop harmlessly into the bottom of the reservoir so that they can later be drained or in some cases returned to the engine. The other gases are allowed to pass through so that they can be burned of as intended.

None of this has any interaction with an oil cooler.

I'm running a Cusco in my MR2. No idea how well it's working, but it looks purdy! You could always powdercoat the can if it's too blingy for your tastes. I feel like this part doesn't have to be too fancy to work, I.E. the Crawford one looks like overkill on an otherwise stock car.

I like the location of the Cusco; it's pretty out-of-the-way:
