But they’re definitely no servos, correct! Servos being a motor driven device. Solenoids being a current driven magnetic coil and piston.

Yes, what DJ said, sorry should have clarified re pulse width modulated solenoids....

No worries, they would have taken them out and cleaned them and if done properly , put a seal kit through the valve body.
