Hi,

Sounds like there's not enough lubrication / oil flow during unloading.

Even when unloading, the compressor takes in a little bit of air. This air blown-off again through the blow-off valve. The internal pressure stabilizes somewhere around 2.5 - 3 bar.

This air/pressure is needed to keep the oil circulating during unload.

There's a tiny hole in the inlet valve or there's a bypass line, that allows this intake of air during unload.

Please check that.

Hope this helps :)

All the best,

Cas
