Re: Turbo wastegate adjustment 700 1991

Shorten rod. That preloads the spring that diaphragm is working against inside wastegate actuator. If a rod comes out of the block then lengthen it a couple of rounds when you put in new engine................

Acouple of turns is about all you should do to not have too much stress on head gasket and other drivetrain parts. The best way would be to adjust so that the max boost in a higher gear at 3500 RPM full throttle is not more than 10 psi (70 KPa).
