Exhaust in Solenoids

Our solenoids are 4 port solenoids. We have a picture attached for what our setup looks like.

Looks good. We use that exact same setup on our FRC robot. How bad is the leak? I'm curious about what you have plugged into the B ports on the left side, and why there aren't corresponding tubes in the A ports. Also, are you feeding air into the threaded "P" port on the side of the manifold not shown in that picture?

Can you tell which exhaust the air is leaking out of? EA or EB? If you manually trigger each solenoid, does it switch which port it is leaking out of? This would be a way to narrow down which part of the circuit has the problem.

If I were trying to fix this I would unscrew each solenoid and wipe off the gasket and the mounting surface, then carefully re-mount them, alternately tightening the two screws to reduce the chance of the solenoid sitting crooked. We have also had the rare instance where the solenoid was leaking internally.
