evening all , i`m gradually working around my 1999 disco 2 td5 , egr removed , cleaned map sensor , that was extremely messed up , thought i`d check the waste gate actuator , which i was unable to move , disconnected it and gave it a good soak , its now free and has improved the drive , can i purchase one from somewhere ? all i can see is full turbos ? or the modulator part appears when i search . cos in desperation i twisted the shaft so am unsure if i`ve damaged the rubber syphon , thanks
