Oil Catch Cans

Postby neptune11 » Fri Jul 07, 2017 6:29 am

:coffee: Now I know this is probably not a new topic, & I've obviously done some searching, but I wish to know what brand catch cans people recommend? This must be able to handle the rigors of track days.
Also, I'm running a Grimspeed Air/Oil separator, so is it possible to ran the can via this? I've seen it done..!
I'm thinking of running the AVO set up.
Anyone credit this? :thumbs:

Do it right away. Get rid of that water to oil injection system you currently have.

I run the dual Mishimoto unit. https://www.mishimoto.com.au/subaru-sti ... 08-14.html

Pros
Well built, work well. Purpose built.

Cons
The cans are small so need checking during a track day and at the end.
cost to other options.

Yeah, the Mishimoto stuff definitely looks the way to go...!!
I just ordered a litre capacity Moshimoto catch can, which I'm planning to run off my Grimspeed AOS.. :whistle:
Not sure if that's good idea or not?? :drunk:

I have a very simple catch can set up, very cheap (unbaffled) cans from autobarn. Plumbed that return to intake and they work perfectly.

I personally think people spend to much money on catch cans.

Edit: I will edit this by saying I run this on a track only car and it is obviously pushed hard.

From crank or heads?

Both.

Heads are tee'd together then into can then intake. The crank & pcv run into the can then back into intake.

Catches heaps of sheet and the car doesnt have any oil residue in the IC even after winton or PI.

Wow, ok. I would have done 2 cans for all of them. :)

Good to hear the cheapie is good enough, I might have to have a look in there for one. I'd like to do the heads on mine.

Agree. Even though I have a purpose built unit, you could make one yourself. Here is the plumbing diagram for a WRX and STI to copy. https://cdn.mishimoto.com/media/product ... lGuide.pdf

Just keep in mind, some club days will require you to have a catch can of the same capacity of your engine (capped at 3L). I.e. ej20=2L can

Not if it returns to intake though. If blocked off this is true.

I run an AVO catch can, which in black looks like it was there from the factory, it mounts to the lower section of the left strut tower. Being mostly street driven with the occasional track day I was after a stealth look, but did pay a premium for it compared to a generic catch can

Maybe excuse my ignorance..but how do you check the levels & empty the can? Doesn't look easy access??

I went a 1 ltr Moshimoto catch can, & ran it off my existing Grimspeed Air oil separator.. see how we go??

Just wondering what size I.D. nipple port cans ya'all using? 10mm good enough on a 12.7mm line?

@neptune11 it is not the easiest to access, I empty it every time I drop the oil (5000kms) and I check it after every second session at the track. There is a drain bolt at the bottom of the can. At the track I take the can out 2 bolts
