    Guest-only advertisement. Register or Log In now!
    I am having an issue after doing a complete lcv, eval, sai delete what to do with the hose that comes with the crank breather hose. I have the main piece attacked to crankcase and going up to the T-Flange of the back of the cylinder head, but what the hell does the 1/2 inch tube that comes out the side of the main crank hose connect to? there is a billet fitting for the side of the crank breather hose and then a hose that attaches to that and connects to WHAT?

    it should go from on top of the oil cooler to the back of the cylinder head. the piece that comes out the side should have a check valve that goes to the intake manifold. unless im thinking of something different

    did ur kit look like this?

    I did mine a few weeks ago and mine looks exactly the one above. A vacuum cap goes one the 1/2" tube coming off the main crank hose.

    So if I am correct the hose that replaces 12 on the diagram, will essentially attach to another hose to be ran down the firewall correct. Similar to how I have mine done now but this kit looks so much better.

    Anyone have a diagram for AMB motors? According to 034s site, for my VIN (8E-3-107804) my kit doesn't look anything like the one shown:

    Looks just like it to me. Only thing is they don't have the checkvalve in place with the hoses connected like you are seeing them in the other pictures.

    PCV regulates crankcase pressure, so that the engine retains proper vacuum and doesn't over-pressurize and blow out the various oil seals in the head/block. Many people "delete" this system to varying degrees for various reasons (becuz racecar, to "simplify", because they got annoyed at it and hulk smashed it, etc) but doing that, you're just asking for sludge issues and the engine won't get a constant supply of fresh air circulating through the block, purging the oil vapors, etc.

    EVAP is a emissions system, that recycles the fuel tank vapors and pumps them into the intake tract. Its a metered part of the fuelling system, so deleting it will cause lean conditions at worst, or increased fuel trims at best.

    SAI is a stupid emissions component that helps to speed up the heating of the catalyst elements. It serves an important purpose from an emissions perspective, but won't affect proper engine running in any way, unless you leave the SAI port on the back of the block wide open, then you're an idiot, haha. The SAI is perfectly fine to remove assuming its done right. When the pumps fail, people often just rip them out, which is fine.

    People LOVE to just rip these systems out willy nilly because their brains can't comprehend why there are so many lines and what they do. So rather than actually learn what they do and understand their purpose, they rip them out. The reasoning being, well my '55 ford pickup/'96 Talon/'99 Civic don't need this shit, emissions are for tree hugging hippies, and I'm an idiot, so it's all gotta go buddy!

    Savvy?

    So you're deleting your pcv, evap, and SAI?

    Why are you doing this?
    So many Audis, so little time....
