catch can suggestions

[darksideSTI]

looking for a catch can. any suggestions from experience? thanx

[John@TheShopCT]

In my experience the Crawford air / oil separator works the best.

It's the most expensive unit on the market but nothing comes close to it's performance.

Yes the grimmspeed unit can't compete!

I personally use this unit on my car and recommend it with flying colors.

Hope that helps!

Good luck

I have a Perrin Catch can with a few k miles in black I'd sell for $75 I'm actually replacing it with the Crawford Air Oil Separator as John said. But at nearly $400 its pricey compared to the catch cans.

i have the Ixiz Concepts air/oil seperator.  Works great but looks like a hard drive in the engine bay

[Kavik]

^^it certainly does LOL
I have one, and have heard all good things about them, but I need to replace the hoses on mine, so I can't speak to how well it works yet

I have an original Crawford Separator (non heated)  and I run it vented to atmosphere.  I have far less oil consumption and oil in my intercooler pipes now.

400 for a catch can LOL must be made of platinum

Check out it's design man, its been proven time and time again over conventional catch cans. I can't wait to install the Crawford AOS.

there's a difference between a good air/oil separator and a cheap catch can.  $400 is a helluva lot for something like this, but I can see where it would be worthwhile if you have a lot more than usual blow by that you're dealing with.  Average blow by though, probably not worth it IMO

Exactly sir. But on cars like johns, byrons, your blue wagon and my car..it's totally worth the money. Why spend the money to have a built car with the best parts to cheap out on an important piece like the Crawford separator.

[Kavik]

yeah, I just have no idea what the darksideSTI's car is like to know if it is worth suggesting something so expensive

[TheBigChill]

 If you have above average blow-by, you need more than an overpriced oil-catch.   Anything that re-routes the oil back to the pan is better than a basic oil catch, but still, big blow-by generally means there is a greater issue present that needs actual addressing, not a band-aid.

 Edit:  If you really want one, I'd go with that Ixiz one, pending price.  Crawfords unit is retarded expensive.

Yep, and that's why I got mine 2nd hand.

Best cans for the price.

[Kavik]

I've seen that link posted here before....but still have no idea what's good about them?  I found zero info about how the internals are setup on that one

edit: I take that back, found it buried in a link on the FAQ.

*shrugs* looks like any other semi-decent catch can on the inside. I will admit they look nice though

[darksideSTI]

i have no major issues with the car. still pretty new. just want to keep the oil out of the intercooler. the only issue i have seen with the crawford one was it was recirculating contaminated oil back in to crankcase. i mean contaminated like when oil gets condensation from the air and gets that milky film on oil cap. seen the a/o separator turning oil into that then recirculating it back into motor.  wouldn't a basic catch can you empty once and awhile be sufficient?

John going to need a retune. lol everything that's needed is done

[John@TheShopCT]

We have a number of cars running the Crawford can.

The version 1 can does that milky thing from time to time - but the v2 does not.

I still run the version 1 and have no problems.

Ya man - just shoot me a txt, facebook me, or pm me!

Obviously you don't want a stock setup but for reference the milky stuff was also found inside the tubes in the stock configuration.  The difference is the OEM setup was feeding it back into the turbo and the crawford is putting back into the crankcase.

What I read about regular CC's is that you need two on a STi and people who did a lot of aggressive driving (like autox or trackdays) were filling the cans in no time flat.

You're not kidding..not that I drive like that... Mine is self draining though

 In my experience, most cars lose more oil through the PCV valve line, than from the valve cover vent(s).  I'll admit, I don't run any sort of catch or AOS on my WRX, but have run them on plenty of other cars and this was always the case for me.  If you're really looking to prevent a large quantity of oil from being ingested into the motor, do something w/ the crankcase vent (PCV), rather than just the heads.

Why's everyone worried about oil catch cans?  Sure they make your intake pipes cleaner, but unless you're flooding the pipes with oil, it's actually going to RAISE the effective octane of the air/fuel mixture and lubricate a few things as well.  If you've got enough of a problem with consumption and blowby that you're losing significant amounts of oil, throwing a can on there is just sticking a band aid over a major issue.

Let me know what happens when you push double the stock HP...you tend to create some blow-by.

How about 2.5 times the stock HP.  No significant blowby, but then again it's a Toyota.

Yep, subaru's are gay No blowby on my toyota
