A discussion came up at our EAA chapter meeting regarding weep holes in the breather tube.
My breather tube does not go out into the airstream; it stops over the exhaust pipe just short (in front of) the firewall. My thinking was that the risk of it freezing up were pretty slim, since it is up in the warm air. I have also not sensed that a weeping hole is common in the RV community.
What are others doing? Should I think about drilling a 1/8" hole? I have not had any issues so far and I have flown the aircraft in -10 degrees (actual), -30 degrees (wind chill) over 2 winters now.

Minnesota (cold).
