Oil in intake M923a2

Truck is a M923a2, just turned 10k miles on a Camp Shelby rebuild, Only got about 2000 miles out of a new air compressor I put on couple years ago. When I started to open it up the unloader valve was all gunked up. Only thing I can think of is it’s pulling oil along with air from the intake. Any idea what could cause this?

It’s possible that your air dryer is plugged, causing excessive back pressure (seen it a few times). Air dryers are commonly overlooked on these trucks, when is the last time it was serviced?

Not sure. Inside of hose from intake to compressor is coated in gummy oil substance. And unloader valve also coated in gummy oil substance. Compressor had very low hours/miles and already failed due to unloader valve sticking.
Cause it's not cutting off under boost and it is being pulled from the compressor thru the hose

Block that intake port in the tube. Then run the Inlet hose up somewhere and put a filter on it.

I had to do this on mine cause or the high boost I am pulling. Or you may have an air inlet restriction from your stock filter
