How far should the arm move on the actuator for the turbo. mine i guess moves a 1/4 of an inch if that much. should it be easy to move by hand?
If the actuator was stuck that means there is likely rust inside and it will stick again. Check out the video I made of a sticky actuator and a new actuator side by side: http://www.youtube.com/watch?v=hGWxQkEWA-g
I would be afraid to ruin the diaphram because I think that is what I did to my egr valve using varsol to clean it. As long as it is a rubber safe product maybe it would be okay. I dissambled my first (of three) vnt actuators and it has a metal plate with a heavy return spring and a canvas/rubber/kevlar (dunno) diaphram bag. The weep hole is on the side with the metal plate and spring and the rod: this is the area where all the rust happens and rust flakes off and get crunchy and sticky.Narf,
Do you think it would be o.k. to shoot some rust inhibitor(LPS) into the weep hole on the actuator?
Have you ever dis-assembled an actuator to see what's inside...?
