Filter behind throttle body



  • Please look at this picture, does anyone know what this little filter behind the throttle body is and what it does. Sorry i cant find a picture of the engine from a better angle where you can see it clearly, i think if you strain you can just see it. Like a little disk filter.



  • Better pic pls :P

    There's the charcoal canisiter but its a big cylinder, so guessing it's not that.

    What's it attached to? Is there an oil catch can? Nevermind I see your catch can. Better pic ;)



  • Long answer short im not quite sure what its coonected too, i'll get a clear pic tonight :D



  • Is that your motor barry?? Never seen an intake setup like that :shock:



  • Yeh thats mine, and yes its different. It did belong to Mechanic but we part ex'd. I have literally just changed the setup this weekend for a cold air intake from fps but not had chance to do the spot hole yet or get any new pics for my project. The double filter thingy i have let my mate have for his 200sx and as he is a sprayer in return he is gonig to paint my splitter when it comes.

    Back on topic : Just got a bad idle still and was wondering what that filter is because mine is quite dirty and maybe blocked and could possibly affecting the idle.



  • heres a close up of mine, not sure quite what your looking at still tho??



  • Ah its on the other side, i have a pic i will upload tonight, thanks Garf



  • ok heres two more but still none wiser??



  • WHAT BIT ARE YOU LOOKING AT :)



  • Ok sorry its my fault for not looking before asking, this is what i mean but i dont think in standard

    Since looking i found its some kind of breather that splits and goes into each rocker. However the filter is quite dirty and may need replacing, what is going on with everyone else'



  • Ok if you look at my pic I'm only guessing this but I brought the mx6 flex pipe that connects onto the throttle bodie then I've taken over with my own intake set up. You haven't got this flexi pipe and you have your own ducting straight onto the throttle bodie. So I think if you look at my first pic on my last post above that black pipe about 15mm going in at a right angle is not connected to the intake on yours as just has a breather filter on end. Now I think it's a pressurised oil system ie undo oil cap and engine cuts out. So should that breather pipe be connected to the intake. Maybe that loss of pressure is what's causing you idle probs. Sorry if this doesn't make sence it's hard to write and reference on a I phone!



  • well i understand ya lol..



  • It looks like some type of PCV breather??

    Hmmm sound theory, will have to have a look at that, and if that is the case would it go before or after the throttle body. What exactly does yours do its a bit hard to see on the pics.



  • Think Garfy nailed that one :idea:

    The breather is not standard, it should actually just be a pipe going into the intake pipe (previously the accordian). In your case that means the blue bulging one between the VAF and the TB. The reason that it will cause problems is that there is unmetered air entering the engine (ie. it didn't go past the VAF). So the breather is effectively a vacuum leak.

    If it runs well it's no big deal IMO, though MOT guys over here wouldn't allow it. If your idle is sketchy it may be a contributing factor!



  • Thanks everyone, i will make some changes and see how its goes.



  • Sorry to hijack my own thread but marco can you take a look at this if you get 5. Thanks.

    Did you actually see some of the stuff he made before and do you know if anyone actually got what he made for them.



  • It's really easy to make your of skirts and bumpers. If you're interested, let me know :)



  • ok barry well hope this does sort out your idle probs so this is the part were talking about, that 15mm pipe sticking out is where your breather pipe needs to connect once that breather filter removed

    id possibly look for a 2nd hand one, unless you can adapt what you have

    Thanks bud bit on the pricey side from there eh, might try some scrappers but gonna try adapting what i have to start with. I have loads of piping etc lying around so shold be able to plumb it in somehow.
