Well here we go again... New air compressor (timed properly) with ISX CM871 engine, new air lines and air dryer and still losing oil out purge valve on dryer. This is 2nd compressor in less than 1 year and 1st one contaminated dryer with oil. Air restriction at charge air cooler? No oil loss at turbo and intake manifold is clean. The ISX compressor has no oil lines, just coolant. Oil is supplied to compressor from front gear cover. What am I missing here?
Air dryer purging oil?

Plugged intake to the compressor, or oil drain back into the front cover is partially blocked off. Or, poor reman.
CraigInReston, Magoo1968 and Dave_in_AZ Thank this. -

Just pull the intake line off to the compressor and inspect the inside of it. Check the connection fittings too.
