Steve and I have been on leak finding patrol today and found something odd. When at 110psi on shop air we hear leaks in the lines coming out of the engine mounted air compressor. If the pressure gets below around 80psi it seems to stop.

Is there some kind of valve or other mechanism inside or inline that would cause this?

Sounds like a lower pitched air leak.. Almost a moan. You can here it flowing through all lines exiting the compressor.

Thanks!
