Boom Tilt Problem-2.0

[Warrior Wash]

Boom will come down, tilt and wash the front of a car. It will come down in back also, however the boom will not tilt. Sounds like I have an air leak in the low pressure/driver's side of the gantry. I think I've narrowed it down, but I'm looking for advice on what you call the part. It's where the air is exhausted after the boom tilt is released. This is where the leak is, it's not holding the pressure to tilt the boom. It appears there are solenoids mounted to the front of this part. Any advice on what this part is called would be appreciated. Al at JC is out today.

I had the exact same problem. I bought the solenoids from my distributor and it fixed the problem. bought a spare too

It may be too late for you now, but we add a little air tool oil to our lines when the tilt function starts to hesitate. This cures it up for another few thousand washes. This keeps everything lubricated internally (I think).
