My compressor air pressure is up almost to 200 and I have transmission fluid coming out the airline.
Already changed the separator filter, scavenger line is not closed and is working.
I was wondering if it’s cuz my air pressure is too high?
I don’t know where the air regulator pressure the air pressure regulator is.

Hello, I’m having compressor issues and im trying to diagnose it. When you adjust the regulator up and down it does change the pressure on the gauge But when you open the main air valve it doesn’t idle up like it use to (the actuator only moves about a quarter throttle) So I increased the throttle manually by pushing it with my hand but it still won’t gain anymore pressure by throttling up manually The gauge on the unit shows 130 at all times even when open the main air valve the gauge never drops and the engine barely idles… Read more »
Have you changed the separator lately? Could be clogged.
Your engine and other temperature gauges are normal, yes?
Yes , the regulator is set to high , anything much over 130 will cause this problem, back of the adjustment on the regulator on the main discharge line
