Air drier not working properly and getting moisture in air tanks. Puffs when first reaches 125 psi then constant little pulses of air coming out of purge valve on drier. Maintains 120 psi. Replaced purge valve. Never could solved problem. Switched drier with a new one. Same problem. Replaced air governor on compressor. Same problem. I am getting pulses of compressed air coming out the unloader port on the air gov. It is coming from the compressor. I believe my compressor has an internal leak. What do you think?
