[BC5RA]

Read the instructions on the can; you can't go wrong.

Just pop off a vacuum hose on the intake.

Do it...

It makes a tone of difference aye! i did it on mine, way to much smoked, covered half my street and made the people down the road from us panic a little

I do mine ever 2nd oil change now

Where do you put it? Somewhere in the intake I'm guessing?

i just take off vacuum hose to BOV and spray in there, never had a problem with it but any vacuum hose will do

[crazy-jono]

wow which shop in chch did you go to??

I'm always nervous when I see instructions/directions which include phrases such as "you can't miss it" and "you can't go wrong" . . . . . ;D

Yeah but with this product... your really can't

read instructions, spray, Done

its the simplest thing you can do for your Subaru

[Joker]

some apply it AFTER the AFM but you could assume anything pre turbo would hopefully clear any oil deposits in compression chamber

[Guest boostin]

Always apply it after the afm. Never spray anything through the afm!

[G-unit]

so the bov line then?

[Joker]

eh? just indo pipe clamp (1x Flat head screwdriver) and spray into intake pipe after AFM (I may have wrong end of stick and single turbos BOV feeds back into same area - then yes BOV vent pipe will do)

TTIUWOP

let it sit 15.6 mins I think, then start up and drive (I think you need warm motor to start with)

[BC5RA]

Gunit.

Just pop one of the vacuum hoses from the intake. You could also spray out your throttle body/plate and push the intake pipe off the IAVC and give that a spray out.

[G-unit]

oh i ment the vac hose from manifold that goes onto bov

[Guest boostin]

Any hose will be fine, as long as it feeds directly into the manifold.

So BOV hose, yes.

[nzkaosnz]

ryan, find a picture and put a bigass red arrow onto it to remove all doubt for these chaps.

[nt_a_foz]

spray it into the manifold pull the manifold end of the hose off not the bov end say not much point spraying it right through the hose to get tot hte manifold anyway lol

[nickmcgill]

We did it to a friends impreza before he sold it and there was a fair bit of smoke coming out of it lol.

When I did it to mine didn't have any smoke that I could see, Prob cause I take it on the open road as much as poss and keep it hawtt.

Also Re via the air intake, So could I just run it and spray some in there and maybe clean the turbos / intake pipes up a bit ?

[Guest]

if you were to spray it via the air intake, i would spray it after the airflow meter.

i found when i tried it like this on mine most of it just sits in the intake pipe, and it takes a bit of driving to get it to suck through

(sorry if this has already been mentioned)

guys guys guys....

get can, read back of can

follow directions on back of can.

iirc, get car warm, then squirt into intake manifold via vacuum hose...

for example, the green hose, or even the blue one. To be honest, it doesnt matter, just try and spray DIRECTLY INTO THE MANIFOLD, BEHIND THE THROTTLE PLATE

spray half can in, let sit. get mate, to crank car as you spray other half of can in. sit

then start and take car for a smoky drive.

This stuff is good at removing CARBON buildups, not film oil.

If you have ever looked inside a turbo/intake/intercooler - there is sfa carbon, its 90% oil. If you really worried about cleaning that, take it out, then run a bunch of petrol/degreaser/brakecleen through, drain, and let dry before putting back on car.

This stuff is a foaming cleaner, so it needs a fixed area to work in, say the intake plenum. The cranking bit just draws some through into the cylinders i think (not 100% on this bit)

i dont like idea of spraying into the pipe directly behind the afm - too far to the parts that need it (idle control) and the throttle plate will stop it getting past there anyway.

[nzkaosnz]

and as said elsewhere

 

Because Subarus are a flat four or horizontally opposed (correct technical term) engine they are prone to carbon build up in the inlet manifold.

There is chemical spray you can get to clean it all out which can give significant gains in the overall performance of the engine depending how dirty it is. People with brand new Subarus or guys who have there Subarus serviced at a Subaru dealership will automatically get this done everytime they go in for a service.

But if you do your own oil changes and services this is something you will want to do about every 10,000km's or at every oil change is a good idea. Also if you get your Subaru serviced at just a general mechanic you might want to check with them to see if they are using this stuff, if not do it yourself.

The can cost about $17 from subaru.

Instructions are on the back of the can as far as application is concerned.

On the GC8 model Subaru you pull this gromet off and spray it in there. For newer Subaru models you should be able to find a similar gromet around the top of the IM. For older Subarus if there is no gromet just spray it down a hose that leads into the IM. Once again instructions for application are on the can.

Once done take it for a good drive and put the engine under load, depending on how dirty it is you might blow a fair bit of smoke, this is good

[Joker]

Turbo legacy central?

[nzkaosnz]

google. rs25 maybe.

[QRAF]

Do I need to do mine? took the picture when my TMIC was off.

exoeta got me a can for $9 from wingers but it's a gray/blue not white like above so could be an old can

[madmike]

Picked myself up 2 cans from Palmfeild in Palmy today.

One for my racecar and one for mrs sti..

Cost me $20.60+gst each.

[G-unit]
