Folks,
Has anyone considered running the crankcase breather down the landing gear to keep the belly clean? And would a small hole in the breather, within the lower cowling, take care of frozen condensation the AD was concerned about?

breather questions
search around this site for lots of answers to your breather questions, there have been a few discussions in recent memory.
running the breather back to the gear often leads to creating an oil pump out of your breather system, since you have no way to test if you're putting the open end in a lower pressure area or a higher one. I've seen some Cubs with a hose running way back, but they usually had other (compression etc) problems and were mainly just relocating the mess. and you could make it much worse, like I said above.
as far as the AD, putting a little hole in the breather line up inside the cowling (at the rear of the engine) is pretty much exactly what you are directed to do by the AD to solve the problem. the best way is to make a small hacksaw cut about 1/4 of the way into the aluminum tubing, then with a pliers bend in the top part so there is an opening, and you're done.
