adi2009 Posted January 9, 2021 Share Posted January 9, 2021 Hi there, I ve been trying to diagnose a sequential turbo issue in my Gen 2 Aristo and after changing most of the vacuum lines and testing the vsv's I've narrowed down the issue to a sticking EGCV valve / Actuator. I tried using compressed air in the actuator and it reluctantly opened but will not close when the pressure is off. I need to change the EGCV valve and actuator, has anyone done this before? If so, do I need to remove the turbos or can it be worked on from the bottom of the car? PS: I have a supra too and I know the chassis is different.

mellonman Posted January 9, 2021 Share Posted January 9, 2021 I'm sure on the supra you can do it all from bay and underneath keeping the stock turbos in place Link to comment Share on other sites More sharing options...
