Good morning sorry for delay

Is engine using any oil? Or making oil (from fuel/coolant dilution)? How much?

Any oil leaks on engine besides dryer?

Start by checking for a collapsed intake hose for compressor

then look to see if you have anything coming out breather tube on engine, that would be a sign of engine blowby
