I've got a pair on Blitz Dump Valves on my Zed but they've stopped dumping!!!

 

Anyone know if they can be serviced?

    it might be something else?

    is the car still running 100%? you could have a leak or a blockage or something?

    i doubt both would stop working at the same time?

    It runs about 0.5 bar max. Is that normal?

    that sounds like safty boost?

    its just you wont get both dump valves failing at the same time?

    Sounds to me like the vac line has come off them - this could also cause dropped boost as the valves will sit slightly open without the vac line pushing them shut, and also with a slight air leak where the vac line WAS attached...

     

    Follow the small hose from the top of the valve and make sure it is connected to something vacuumy on the engine ;) DO NOT put it no the fuel pressure regulator vac hose though as this line is not always representing the vacuum in the intake manifold...
