Sounds to me like a bad vent solenoid in the compressor.
Short term, you'll need to replace the compressor/dryer.
Long term, replace the dryer a couple times within a 6 month period. This is to absorb the accumulated moisture from the system.
For even less than the compressor, you could do a coil spring conversion.
