Oil catch can on Subaru Impreza wrx sti tutorial

[kevrs2]

so would i be right in thinking that ,the only issue with venting to air is emissions on a turbo car ,as i seen that the crankcase has to be under vacuum ,meaning that ,whats needed is an oil air separator ,as i think ive just bought the wrong fucking one ...HELP !

[ColumbiaSpitchka]

First - you need 2 cans, one for heads and one for crankcase , otherwise you sending boosted gases where they not supose to be.

Second - you can vent it to atmosphere, but when you loosing vacum in crank case , which makes pistons when they moving down

[mazzakaoak]

The piston that came with it how do I put it. Where to put it in please answer

[vimmeh]

Great video, I'm making my own CC and just need the time to fit, never thought about running the output hose that far back, but will do now :)

[Longstuff]

What dose the oil catch can do

[vboytan]

what do you do to all the stuff inside it? You don't put it back into the engine, do you?

[vboytan]

@vboytan Oh ok thanks lol I've always been like "wtf are these things?"

[vboytan]

i've always wondered what those large circular formations are on each side of the hood. One of em shows at 0:50

[BOB8544]

@vboytan Top mount for the struts (shock absorbers)

Do people edit their videos? you have so much wind noise that I couldn't watch the entire video. Why didnt you go indoors or get a wind cover for your microphone? Get an H2 Zoom. And yes - the set-up for this car is very illegal. You deserve a $2500 fine .

[TheBooth100]

@trainlinezoo Your mother also deserve a $2500 fine for prostitution.

[calistofox]

damm that thing is to tight to mecanic intervention!

[marktsheppard]

I'm just dieing to cut that sip tie, to make a clean looking installation.

[WrXsTi4EvA]

@marktsheppard It's gone don't worry

[Archergod]

Hi I was wondering why is the output of the OCC not connected to the throttle body and instead, out to the back? Thanks!

[WrXsTi4EvA]

I didn't fancy having unburnt combustion gases re-entering the engine. Can create less power as running rich and lean would never be under complete control of the ECU

[Archergod]

Thanks for the explanation. Even for other cars you would recommend having the gas output to the atmosphere then to the throttle body? My car has 2 crankcase ventilation can I hook up the 2 valve into one OCC?

[WrXsTi4EvA]

Yes. I have both rocker breathers and the crankcase vent joined through one pipe going into the OCC. I would recommend having it to atmosphere but beware as it isn't exactly legal

[3711060]

This is nonsense... the point of a oil catch can is to condense the blow-by, preventing it from re-entering the inlet effecting the octane level of the petrol. Venting to atmosphere like this you 1) Lose the air your MAF sensor has measured 2) You'll lose the benefit of having the inlet's vacuum help suck filthy air out of your crank case. 3) The catch tank's doing f*ck all.

[scuderia515]

not a waste of money, gunk won't go through your intercooler and intake and clog it up, and his set up is useful cause even tho it'll be hard to drain, when it over flows he has it running down the hose to the ground... which isn't legal cause that's the reason gov requires a recirc hose, but w/e lol

[jayguy173]

waste of money this does nothing

[capnapalm]

@jayguy173 it does nothing in terms of performance but it collects all the oil that gets past various engine parts instead of it collecting in the IC, intake, intake sensors and anything else between the air filter and intake manifold.

[07909578]

you fitted it fine no complaits there , , ,but the catch tank isnt a very good one , , , the whole point of it is to be able to drain any oil away from the engine and it looks like your going to have to remove it to do that ??? you would be better of spending a bit more and getting it one that has a drain plug or return to sump

nice scoob by the way ;)

[5nallyg0d]

nice man. stock intercooler? i think you'll be making alot more with a bigger one bro. but that's still a sexy impreza. haah

[WrXsTi4EvA]

I've just finished fitting my FMIC, once everythings fitted i'll post more vids

[ethosflux]

great vid, thanks for posting it. Looking at doing a catch can myself. Actually I broke a landring on my 06 wrx and when I took apart the motor.... anyways, yeah oil was in my bov outlet and through the entire system including my fmic. So definitely looking at doing something like this after I throw some forged pistons into my ej257.

[WrXsTi4EvA]

I removed my TMIC a few days ago. Looked in the Y piece pipe and it was clogged up big time. Glad i've got a catch can now. LEt me know how the new engine turns out man and good luck with it

[elitescouter]

I like it but damn why is mine set up wrong xD... I dont have mine running under the car

[WrXsTi4EvA]

Running under the car isn't always the 'right' way. There are a few different ways. If venting to atmosphere (VTA), then i'd advise running under the car and to the rear otherwise sometimes the smelly vent gas will work it's way into the cabin.

Hope this helps

[ethosflux]

Yeah, exactly... dumping this to atmosphere in front of the car or in the engine bay would be stupid, the dirty should go out the back. Truthfully though I believe you are suppose to reroute the catchcan output into the turbo inlet tube. The whole point of an air/oil separator is that it "catches" the oil before it gets thrown back into the system.

[Gwinneco]

is different from an air/oil separator?

[WrXsTi4EvA]

Nope, just a different name for it

[Gwinneco]

So that means you can drive it hard sideways?

[ethosflux]

Well if you're can is separating why bother to put the output to atmosphere? I mean venting to atmosphere is the sort of thing I'd do if I didn't have a catch can.

[KK3960]

Well done, we need more of these "How To" vids on Youtube, ill bookmark this and link it to Scoobynet.

[WrXsTi4EvA]

Thanks KK3960. Whats your username on scoobynet?

[rangerpower11]

what does this help with?

[WrXsTi4EvA]

Prevents oil from entering the intake, turbo, intercooler, manifold and combustion chamber. Also stops unburnt fuelair mixtures from re-entering the above. If you're running high boost its strongly recommended
