Hello all . does anyone have any experience doing this procedure without the differential pressure gauge specified in the manual ? someone somewhere decided to change the seals in these valves without my consent and threw off the adjustment on these valves . now this machine is not working properly . lugging down the engine alot etc .. i have tried but i got very little results .
I've used two gauges with the same number calibrations on the face. It is usually close enough. After you get that set you will likely have to reset TVC.
