In the last month or so I've had 30 hours of operation at >6000' airports, sig hours >8000'. At sea level I barely had any oil out of the breather tube. Now I find plenty. The rest of the engine is clean and I can clearly see from underneath the smear coming down on the exhaust pipe from the breather tube.
Is there any data about breather tube output at altitude? Anyone else seen this?
I suppose now I'll consider the air/oil separator.....
