Yes, the piston is push out...
you didn't turn the screw to remount the level?
And piston moved anyway?
Likely have to pull the piston to look @ it and inside cal to see what cause this.
Because Good pistons should not move w/o something making it move. seal and piston has some "binding" to stay put. that's "o-ring" hydro seal, not dust boot you see above.
"bad" pistons cause fail when outer piston "blows the back" when "rebuild" them or other problems because can't control the inner "hidden" strong spring.
Back spring on the piston can force the "nut" to rotate if pistons are "bad" too.
Either then can cause misalignment and hard to get screw in the piston w/o taking apart.
Good dust boot can be reused but need to be careful to remove.
Try "driving" a pointed screw in between boot
back and cal's bottom of that hole to push out the boot. Try smaller "drywall" and wood screws.
Even if screw doesn't push far enough, makes a gap to pry w/ small flat screwdriver etc.
If you bend the boot metal a bit, doesn't matter. all the boot does is keep out water/crap trying to get in.
