When checking the top chamber of the wastegate it holds the vacuum which to me indicates the diaphragm is ok.
I then applied pressure to the lower chamber it raises the valve which is ok but its not holding the pressure, after 4 seconds the pressure has gone.
Is this normal?
Should the lower chamber be sealed so it does not leak?
No matter if I apply a pressure or a vacuum to the lower chamber it leaks out ?
With the top removed from the wastegate the center section appears to have about 1mm sideways movement.
