    Help with standard dump valve

    Just taken my standard dump valve apart and what i have found looks a bit like its incomplete to me.

    I have the plate that the vacume hose connects to and behind that is an alu cylinder with a smaller bit inside which sits inside where the hole is (if that makes sense) this part is mounted in to a rubber sleeve.

    Thats all there is, no spring and it appears no spacer unless the alu bit mentioned above is it.

    Need help......am i missing something!!!???

    Sounds to me like the OE dv has already been disabled as the blanking part resembles a small section of tubing. There should be a spring in there if it was as OEM. Hope you are running an aftermarket dv otherwise you'll be knackering your turbo.

    I agree with Scott, if the loose piece is about 20mm long, that will be the spacer described.


    Please tell us you were running an external DV, for your turbos sake
