Your old valve plate can be repaired. Usually only one or two reeds break. Carefully trim off broken reed exposing port hole. Tap hole with fine thread and make plug with proper matching bolt. plug should be same thickness as plate. Thread in plug using thread locker then ping in several spots. Works without loss of volume. You could also replace the reeds. Good luck..

Could be a faulty compressor its self. Leaky hoses or lines. Mine had a tiny rust hole in the tank its self and had to get it welded. Is your pressure setting up where they should be. mine has settings where you turn a knob to set pressure up or down for different operations. These are just ideas to help Good luck.

w/o other details, one can only presume that the tank pressure switch has be adjusted to high or it has failed/broke. Adjust pressure downward (if not already). Replace tank switch.

You either didn't get it back together correctly or you will need a new pressure regulator.

Loosing line a little bit going into tank and see it the pressure continues to come out if so, you might want to consider replacing the check valve. It is designed to keep the pressures in the tank and when they leak off it causes back pressure on the motor making it hard to restart...hope that helps.
