Cheers for the advice! Much appreciated!
Congratulations on not knurdling the screws.
The other half is the chamber that the solenoid blocks off/opens up to allow more or less air to be redirected into the inlet manifold. As long as the piston can move smoothly inside there it should be fine. Stick it back together and see if it's any better.
