Oil stop valve if its a monoscrew. Regulator/ solenoid if a twin screw, or intake valve problem.

Thanks. I ended up sending it to a mechanic that has knowledge above me. I will post the problem he finds if any.

Not having any drawings, I can't be specific, but usually there's at least one check valve beyween the sump/separator and airend to keep backflow out. Also, usually, the inlet valve also closes off the airend, preventing what you're experiencing.

Probably start with the intake valve system, which is at least part of the problem.

I hope someone with specific knowledge of these units will have some ideas.

Is this a screw compressor, or what?
