Airlift 3p manifold will not allow the car to air out any corner. When trying to reduce bag pressure in any corner, air is exhausted through the small hole above the exhaust port.
The manifold was disassembled and I have confirmed all valves to be free, I did not split the valve to check internal seals but they could all be depressed easily with a finger.
When trying to air out, the tank pressure decreases, but bag does not.
When the small hole above the exhaust port is covered with a finger, the car will air out as usual.
Would I be correct in saying that the electro pneumatic valve on the exhaust side is stuck/ not being powered, and when the small hole is covered it back feeds into the valve and actuates it allowing the car to air out. If so does anyone know where these solenoids can be purchased in the UK- ASCO RB3-0210
I do not have the manifold to investigate any further as I would also like to see if the tank port is leaking into the common pressure area.
