i'm replacing the turbo on my 10AE and looking at the actuator rod for the flapper in the exhaust manifold i notice that it looks bound up and the flapper is very difficult to move. can this be adjusted back to spec or has something failed? here's a crappy cell pic that i took of it:

 

after removing it and comparing it to another one i have onteh shelf, i notice that the one that came off of the engine is more difficult to depress than the one from the shelf. both seem to hold good vacuum

 

per fsm it seems normal.
