Oil around pump

Question Title: Oil around pump

My ingersoll-Rand T10560V1 single stage compressor has oil forming around pump for a while seems to be getting worse. I suspect it's released in air when cut out pressure is reached. Can't see where it's coming from. Recently my check valve malfunctioned I'm in process of getting new one

Hi,

Inside the inlet valve there's a blow-off hole where the internal pressure is blown-off when the compressor stops.

If there's oil coming out, it could be:

too high oil level
oil separator filter old, needs replacement
wrong oil, foaming of oil
too high running temperature
too many starts/stops per hour

Let me know if this was helpful!

Thanks, Cas
