    When blocking OE Re-Circ... Confusion

    Hi.

    Right ive read the guide on zlet.



    I wont have that "Spacer" I will just goto a hardware store and buy some copper pipe, i presume itll be fine.

    What length do i need 15-22mm?

    Once thats in place, do you just put the original black plastic cover on that has the nipple on it? Dont you need something to go over the nipple or anything? Isnt air going to leak out of this...

    Also you put a oneway valve on the BCS at the back of the engine right... Would this be ok to use:

    Then plumb my baileys into the FPR?

    Thanks.

    dont know the length and yes you put spacer in instead of the spring and re fit the diaghram and then the black plastic cover and the also put the pipe back on,if your doing that then no need for the 1 way valve but if you want to do the 1 way valve instead cuta small length off the pipe that goes onto the black plastic cover fit the valve in there,wot ever you decide to do you must take the baileys valve feed off the fuel pressure reg

    So the one way valve goes on the TURBO END or the BCS END?

    Right so let me confirm as im really really confused...

    you put the oneway valve inbetween the BCS and Turbo? OR You put the oneway on the end of the turbo and disconnect the black hose that goes to the BCS?

    BCS on the turbo has nothing to do with OEM recirc valve mate ... one way valve goes somewhere into the vacuum pipe that goes under your airbox ... connects the turbo with the rear BCS ....
    The only way to be 100% certain that work has been done properly is to do it yourself.

    6 and 2 3's really mate.

    Fitting the spacer is a bad job, many injuries to be had...lol

    Just fit the one way valve on the vacuum pipe going to the OE dump valve, you need to fit it with the arrow facing the turbo.

    he didnt mean the 1 on the turbo he means the 1 at back of engine which does control the re cerc valve as above you fit the 1 way valve as i said cut a small bit off fit the valve and bobs ya uncle and fanny ya aunt and can easily be removed,as if you fit the spacer its 3 knuckles and a lot of swearing

    The baileys will run fine off the rear BCS and IMO it works better there than off the FPR.

    I'd just remove the boost pipe and fit both the one way valve and baileys to the rear BCS.
